Thomas: The Faith That Doubts and Believes Without Seeing

Introduction

After Easter, there's a question you don't always dare to say out loud: do you still need a sign from God to believe? The disciples saw the risen Jesus. They got their proof. But you, today, maybe you're like Thomas: the one who wasn't there that evening, the one who asked to see the nail marks before believing. This Momentum sermon on John 20:19-30 takes that question seriously. It starts by reminding us why the resurrection is the absolute center of the Christian faith, then looks closely at the encounter between Jesus and Thomas. And it ends with good news: the sign you're looking for, God has already given it.

Sermon outline

1. The resurrection: the central point of our faith

• The preacher opens by saying he feels both excited and a little nervous, because this is the greatest theme in the Bible and the central element of the faith: the resurrection of Jesus Christ.
• At Easter, we rejoiced. We had seen Jesus mistreated, humiliated, condemned despite his innocence. His death put an end to his suffering. But above all, he rose again, and that changes everything.
• This resurrection is hard to believe. Someone who dies and comes back to life: it's strange. Yet Paul writes it plainly: "If Christ has not been raised, then our preaching is in vain, and your faith also is in vain" (1 Corinthians 15:14). The whole of the Christian faith stands or falls with the empty tomb.
• Without the resurrection, everything we do at church (the singing, the fellowship, the prayer) means nothing. With it, everything makes sense.

2. Jesus comes into the midst of the locked-in disciples

• John 20:19: "When therefore it was evening, on that day, the first day of the week, and when the doors were locked where the disciples were assembled, for fear of the Jews, Jesus came and stood in the middle, and said to them, 'Peace be to you.'"
• The disciples are locked in. They're afraid. Their hearts are locked too, weighed down by disappointment and doubt. And yet Jesus comes. Locked doors don't stop him, and neither does fear.
• His first word is "Peace be to you." Not a rebuke for their fleeing, not a reminder of their betrayal. Peace. That's the direct fruit of the resurrection: because Jesus is alive, he himself brings peace to his own.
• He shows them his hands and his side. The risen One is indeed the crucified One. The scars aren't erased. It's proof that this isn't a ghost or someone else, but Jesus himself. His death and his resurrection can't be separated.
• So the disciples rejoice "when they saw the Lord" (John 20:20). Fear gives way. The presence of the risen One turns everything around.

3. Sent as Jesus was sent

• John 20:21: "As the Father has sent me, even so I send you."
• Jesus came to earth to reconcile rebellious humanity with their Father. He accomplished that mission through his death and resurrection. Now he passes it on to his own. The Father and the Son send the Holy Spirit together, and the whole Trinity sends the disciples out to bring the lost home.
• It's the same sending as in Matthew 28:18-20: "All authority has been given to me in heaven and on earth. Go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I commanded you. Behold, I am with you always, even to the end of the age."
• Almighty God has decided to use you, you who believe, to speak to the lost. It's not your charisma that will make the difference: it's his presence in you and the word you proclaim in his name.
• The preacher shares a personal example: this week, he drove across the country to see someone he was worried about. He didn't know what to say, so he asked his small group to pray. He watched that person's eyes open to the lie they'd been living in and recognize that their real problem was their sin and their distance from God. He came home grateful but a little unsettled, because for now, that person hasn't yet chosen Christ. Proclaiming the truth in love is the right thing to do, even when it's costly.

4. Receive the Holy Spirit: you don't carry out the mission alone

• John 20:22: "When he had said this, he breathed on them, and said to them, 'Receive the Holy Spirit!'"
• There's a debate about this verse: do the disciples receive the Spirit at this very moment, or is this a preview of what will happen at Pentecost? The preacher doesn't take a side, and notes that Jesus had said he had to leave for the Spirit to come (John 16:7).
• Either way, one thing is clear: this text isn't describing two baptisms of the Holy Spirit. There's a single conversion in which the Holy Spirit comes to live in the believer. If you believe Jesus is risen, the Holy Spirit lives in you. That's the promise.
• Verse 23: "Whoever's sins you forgive, they are forgiven them. Whoever's sins you retain, they have been retained." Jesus isn't handing the disciples God's role. He's giving them the role of proclaiming the truth. Those who come to the Lord will be forgiven; those who refuse remain under their sins. Our part is to open our mouths and announce the gospel; the rest belongs to God.

5. Thomas: the skeptic of skeptics

• John 20:24-25: "But Thomas, one of the twelve, called Didymus, wasn't with them when Jesus came. The other disciples therefore said to him, 'We have seen the Lord!' But he said to them, 'Unless I see in his hands the print of the nails, and put my hand into his side, I will not believe.'"
• Thomas missed the first meeting. He sets his conditions: see, touch, verify. A full eight days pass. Eight days in which he refuses to believe, despite the unanimous testimony of his friends.
• The preacher illustrates this human blind spot with a simple experiment. Take a rope that goes all the way around a bucket. Add one extra meter of rope: it now sits about fifteen centimeters away from the bucket. Now take a rope that goes all the way around the earth, over forty thousand kilometers. Add that same one meter. How far does the rope move away from the ground? Still fifteen centimeters. A simple math formula proves it. We resist believing it, even when the proof is right there.
• The lesson: we all decide to believe in something. Deciding not to believe is itself believing there's nothing there. It's no more rational, no more intelligent, than believing in Jesus.
• John tells this story because he knows how hard the resurrection is to accept. Thomas is us.

6. "Don't be unbelieving, but believing"

• John 20:26-27: "After eight days again his disciples were inside, and Thomas was with them. Jesus came, the doors being locked, and stood in the middle, and said, 'Peace be to you.' Then he said to Thomas, 'Reach here your finger, and see my hands. Reach here your hand, and put it into my side. Don't be unbelieving, but believing.'"
• Once again, locked doors. Once again, Jesus comes. Thomas's heart is locked one hundred percent, and Jesus comes anyway. He doesn't rebuke him at all. He meets him exactly on his own terms. He knows each of us by name, and he comes to meet our faith wherever it stands.
• His words in the Greek carry more force than our translations show: "Stop not believing, and believe." It's a call to leave unbelief behind and step into faith.
• Verse 28: Thomas answers, "My Lord and my God!" It's the first time a disciple addresses Jesus this way. The skeptic of skeptics, on seeing the risen One, confesses his divinity. Because the resurrection proves that everything Jesus said is true, including that he is God.
• Verse 29: "Because you have seen me, you have believed. Blessed are those who have not seen, and have believed." Jesus isn't mocking Thomas. He affirms his confession, and from that confession he pronounces a blessing on everyone who will believe without seeing. The same peace, the same joy the disciples had, for you who haven't seen.

7. A sufficient sign: the resurrection

• Thomas got his sign. And what about us, do we get one too? Yes. But not the one we ask for. The sign is called the resurrection of Jesus. And it has already been given.
• John 20:30-31: "Therefore Jesus did many other signs in the presence of his disciples, which are not written in this book; but these are written, that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name."
• John made a selection. He could have told a thousand other things. What he put in his gospel is enough for you to believe that Jesus is the Messiah and the Son of God. The most important sign is his death and his resurrection.
• Christian faith isn't a vague confidence in something fuzzy. It's a belief with real content: a person, Jesus, what he accomplished, and his resurrection. If you think you have faith but you don't believe Jesus rose again, you're still under the weight of your sins.
• The result of this faith is life in his name. Eternal life, as Jesus himself defines it: "This is eternal life, that they should know you, the only true God, and him whom you sent, Jesus Christ" (John 17:3).

Key takeaways

• The resurrection is the absolute center of the faith. Without it, the gospel collapses. With it, everything holds together.
• Locked doors don't stop Jesus. He comes right into locked hearts, bringing his peace, without a single rebuke.
• The risen Lord sends out his own. His presence in you, through the Holy Spirit, is what makes the difference, not your eloquence.
• Doubt isn't the end of the story. Jesus comes looking for the Thomases and gives them exactly what they need to believe.
• The sign has already been given. You don't have to wait for anything more than what God has already recorded in the gospel: Jesus died, he rose, he is alive.

Personal application

• Where are the locked doors of your heart right now, fear, disappointment, routine? Have you invited the risen Lord to come and stand in the middle of them?
• Are you still waiting for some special sign to believe, when God has already given you the empty tomb and the testimony of Scripture?
• Like Thomas, what condition are you setting for God today before you'll believe? Are you willing to let Jesus meet you on his terms, not yours?
• Who is Jesus sending you to this week to proclaim the truth in love? Whose name are you willing to carry before him in prayer?
• If you confessed today, like Thomas, "My Lord and my God," what would that actually change about your week?

FAQ

Do I still need a sign from God to believe?

No, God has already given that sign: the resurrection of Jesus Christ. John writes at the end of his gospel that Jesus did many other miraculous signs, but the ones recorded in the book are enough for you to believe that he is the Messiah, the Son of God, and that by believing you may have life in his name (John 20:30-31). The sufficient sign is an empty tomb and a living, risen Lord.

Is it a problem if I doubt like Thomas?

No. Thomas doubted for a full eight days after the other disciples' testimony, and Jesus did not reject him. He came especially for him, through locked doors, and said: "Don't be unbelieving, but believing" (John 20:27). You too have a place at the table of the risen Lord, questions and all. What matters is that you don't stay in your doubt, but that you come to Christ so he can answer you.

What does the resurrection actually change in my life today?

Three things. First, if Christ has not been raised, your faith is worthless and you're still carrying the weight of your sins (1 Corinthians 15:17). His resurrection proves that his words are true and that his death paid for you. Second, he sends you out: "As the Father has sent me, even so I send you" (John 20:21). Finally, he gives you life in his name (John 20:31): peace, joy, and a living relationship with the Father through the Holy Spirit.
