Salt and Light: Christ's Anointing, Not Your Own Effort

Jesus didn't just tell you, "Be salt, be light." In Matthew 3 and then Matthew 5, he opens up the source for you. At the Jordan, he receives the anointing of the high priest; on the mountain, he declares that this anointing now flows over you. Your saltiness and your light don't come from your own effort: they come from him.

Introduction: a command that comes with the power to fulfill it

In Matthew 5:20, Jesus drops a line that takes your breath away: "For I tell you, that unless your righteousness exceeds that of the scribes and Pharisees, there is no way you will enter into the Kingdom of Heaven." Then, just a few verses earlier: "You are the salt of the earth… You are the light of the world." (Matthew 5:13-16). The bar is set very high. Reading it, you might find yourself saying, as Hugh WESSEL once put it, "Lord, have mercy on me, because I can see clearly how high that step is."

But here's the good news: Jesus didn't just give the command to be salt and light. He also provided the status and the power to become it. Your ability to be salt and light isn't a performance you produce. It's your identity, a character transformed and defined by the Beatitudes. And Jesus sealed that identity for you at the Jordan, on the day of his baptism.

Outline of the message

1. The baptism of Jesus: a priestly consecration (Matthew 3:13-17)

Picture the scene again. Jesus comes from Galilee to the Jordan, to John, to be baptized by him. John hesitates: "I need to be baptized by you, and you come to me?" John knows exactly who he's dealing with: his cousin, the Son of God, perfect. John's baptism was a baptism of repentance. But Jesus has nothing to confess. So why does he step into the water?

Jesus's answer is decisive: "Allow it now, for this is the fitting way for us to fulfill all righteousness." Which righteousness? The only one that existed at that moment: the righteousness of the Old Testament. By asking to be baptized, Jesus points you back to the consecration rites for priests described in Exodus 29 and Leviticus 8. A priest was consecrated through water, the anointing of oil, and ceremonies. The word "baptism" doesn't appear there, but the idea does, and Hebrews 9 confirms it, speaking explicitly of the "baptisms" of the old covenant.

At the Jordan, Jesus is about thirty years old. He officially enters his public ministry as our great high priest. Some will say, "He was baptized to identify with humanity." But that's not what the text says. It was his birth, his incarnation, that already identified him with our humanity. Here, he takes up the office of high priest to represent the people before God.

A detail that matters: Jesus was born of the tribe of Judah, not Levi. So he shouldn't have been able to carry out a Levitical priesthood. The New Testament sheds light on this: he is a priest after the order of Melchizedek, a universal priesthood (Hebrews 7). Had he been confined to the Levitical rites, his priesthood would have been limited to Israel. But the Gospel needed to reach the elect of the whole world. Where the Pharisees sought righteousness for their own glory, Jesus fulfilled righteousness for your salvation.

2. Jesus, our source of salt and light

Because he is the perfect high priest after the order of Melchizedek, Jesus is your source of salt and light. He's not simply someone who teaches you. He is perfect. He is the pure salt that never loses its flavor. He is the spotless light that darkness has never been able to snuff out.

Let's say it plainly: darkness has never overcome Jesus. Never. He is light, and he has won. He defeated the darkness at the cross, once and for all.

Jesus fulfills three offices on earth. Prophet: he announces the word of God, he enlightens minds, he reveals truth. That's exactly what he's doing in the Sermon on the Mount, explaining the righteousness that must exceed that of the Pharisees. Priest: he intercedes, he preserves his people. King: he governs all things with perfect justice.

When Jesus declares, "You are the salt of the earth… you are the light of the world," he doesn't say, "try to be." He says, "you already are," with a vital implication underneath: stay attached to me. The Bible confirms this everywhere: he is the vine, you are the branch; apart from him you can do nothing (John 15). You know full well you can produce nothing without the presence of the Holy Spirit in your life to enlighten you, help you, and transform you.

3. The role of the Holy Spirit: the anointing that flows from the head to the body

Back to the baptism of Jesus. "The heavens were opened to him, and he saw the Spirit of God descending as a dove, and coming on him." This isn't just a symbolic gesture. The Holy Spirit comes to remain on Jesus. Just as Isaiah had prophesied, the Messiah is publicly anointed for his mission.

Two Old Testament texts help you grasp the full weight of this anointing.

Psalm 133 pictures the oil poured on Aaron's head, priest according to the Levitical order, oil that runs down his beard and onto the edge of his garments. A blessing that unites and spreads.

Isaiah 61 announces the anointing received by the Messiah for a mission: to proclaim good news, to heal, to set captives free. Together, these two passages tell you that the anointing comes down on the head and works through the body.

It's a perfect picture of the priestly anointing. The oil doesn't stay localized on the head; it flows from the head down over the whole body. In the same way, the Spirit of God unites you to God and fills you with power in his presence.

At the Jordan, two dimensions come together: the water, marking a visible, public consecration; the Spirit, communicating divine power for ministry. And the Father's voice can be heard: "This is my beloved Son, in whom I am well pleased." Three persons of the Trinity present at the same time in a single passage: that's rare, and it's right there.

Why did Jesus want to receive this anointing? Because, in his true humanity, he chose to be dependent on the Holy Spirit himself. And he is your model. The same Spirit who filled him for his mission fills you today for yours. Your ability to be light doesn't come from your efforts or your desires, but from the anointing of the Holy Spirit in your life. Just as this anointing came down on Christ, your head, it now flows through his whole body, meaning through you.

What's the proof? The day of Pentecost. At the cross, Jesus said, "It is finished." And the Holy Spirit comes down again, but this time not as a dove: as tongues of fire. The people aren't consumed. Why the fire? To remind you of God's holiness and to tell you that this Holy Spirit isn't going to devour the people, but to dwell in them. Paul says it: "one baptism" (Ephesians 4:5). The true baptism is the baptism of the Holy Spirit, of which water is only the visible sign.

4. Your identity: a royal priesthood (1 Peter 2:9)

Your baptism (and that of your children) declares publicly that you belong to the people of God. It's the visible sign of an invisible reality. A way of putting a tag on the garment: "Here is the people of God, here are the lights of the world."

Each one of us has a calling. Just as Jesus was anointed for his priestly ministry, you are, by the Spirit, brought into the royal priesthood. Peter says it powerfully: "But you are a chosen race, a royal priesthood, a holy nation, a people for God's own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light." (1 Peter 2:9).

Set apart and consecrated not by your efforts, but by the work of Christ. And God has placed you in the church to fully live out this identity as one who is consecrated, and to proclaim his praises, as we try to do at every service.

5. The Sermon on the Mount: an instruction manual, not a guilt-trip checklist

This changes everything about how you read the Beatitudes and the Sermon on the Mount. It isn't a list designed to make you feel guilty. It's the instruction manual for your new nature.

The Pharisee says, "God, look at what I'm doing." The disciple says, "I'm someone consecrated in Christ, so I live like him." That's not the same logic. One accumulates in order to make himself worthy. The other receives an identity and lives it out.

The righteousness that exceeds that of the Pharisees is the righteousness Jesus fulfilled at the Jordan and now offers to you today. It isn't your righteousness, but the righteousness of Christ, given to you freely.

6. Your children, too, share in the covenant

One last point that matters for church life. The tribe of Levi was set apart in advance to serve as priests: every child born into a Levite household entered that calling by birth itself. Under the new covenant, the same principle applies in a renewed way: your children born into a Christian household share in the covenant. They grow up, as each of us does, as priests, kings, and prophets of Jesus Christ. We intercede, we reign in his name, we proclaim his word.

In a world where everyone proclaims, "I'm the one who decides, I'm the one who matters," it's easy to slip back into the Pharisee's logic: me, me, me. A disciple's answer, though, is short: Christ. My identity in Christ. Christ has done everything for me and my family.

Light needs a power source

Have you ever seen a lamp with no power supply? It doesn't shine. Light needs a power source to shine. Christ is your source. The Holy Spirit is the current burning in your life. You don't need to manufacture your own light. You look to your Lord, and you find yourself amazed, sometimes without even realizing it, to be shining in the middle of the darkness. It isn't primarily your good works that the world sees: it's Christ shining through you.

Personal application

1. Where are you tempted to fall into the Pharisee trap: justifying yourself by what you do rather than by what Christ has done? In which area of your life this week (work, family, prayer) are you still leaning on your own effort instead of leaning on his anointing?
2. How do you read the Sermon on the Mount now: as a crushing checklist, or as the instruction manual for your new nature? Pick one Beatitude this week and ask the Spirit to work it out in you.
3. If you are a Christian parent or grandparent, how do you talk to your children (and grandchildren) about their place in the covenant? Are they being encouraged to see that, in Christ, they are priests, kings, and prophets?
4. Is your baptism (the visible sign of an invisible reality) a living memory for you, or a forgotten event? Return to that reality: you are marked as belonging to God.
5. When you feel the weight of "not salty enough, not bright enough," what do you do? Jesus's answer isn't "try harder" but "stay attached to me." How will you stay attached to him this week, concretely?

Key takeaways

• Jesus gives the command and supplies the power. He didn't just say "be salt and light": he provided the status and the energy to become it.
• The baptism of Jesus is a priestly consecration. He isn't repenting; he's officially stepping into his ministry as high priest after the order of Melchizedek.
• The Holy Spirit's anointing flows from the head to the body. Poured out on Christ at the Jordan, it now flows over you who are in Christ.
• You are salt and light by identity, not by performance. "You are," Jesus says, not "try to be."
• The Sermon on the Mount is an instruction manual. Not a list meant to crush you, but a description of your new nature in Christ.
• You are priest, king, and prophet. 1 Peter 2:9 defines you: a royal priesthood, set apart by the work of Christ, not by your own efforts.

FAQ

Why was Jesus, who is without sin, baptized by John the Baptist?
Not to repent (he had nothing to confess), and not merely to identify with humanity (his incarnation already did that). He was baptized to be publicly consecrated as high priest, following the logic of the consecration rites in Exodus 29 and Leviticus 8. His answer to John is clear: "Allow it now, for this is the fitting way for us to fulfill all righteousness."

What does "priest after the order of Melchizedek" mean?
Jesus was born of the tribe of Judah, not Levi, so he could not carry out a Levitical priesthood, which was limited to Israel. Melchizedek is a universal priest in the Old Testament. Jesus, a priest after this order, exercises a perfect, eternal, and universal priesthood, accessible to the elect throughout the whole world.

If I am "already" salt and light, why don't I always feel like it?
Because you're sometimes mixing up your identity in Christ with your performance in the moment. Jesus tells you, "you are," not "try to be," while also adding: stay attached to me. Your light has a source (Christ) and a current (the Holy Spirit). When you feel flat, don't fix your attention on your own effort: return to the source, and let the Spirit flow again from the head to the whole body.
