1 John 2: Eternal Life Begins Now

Introduction

"We are living today in a society that is changing very fast." This is how Jesse Rose opens his message on eternal life, delivered at the service on September 20, 2026, from 1 John 2:24-25. The message is preached in English and interpreted into Japanese for the congregation.

Throughout history, he reminds us, human beings have always carried two questions, and they remain essential today: what is truth? And what is a good life?

The text for the day is short: "Therefore let that remain in you which you heard from the beginning. If that which you heard from the beginning remains in you, you also will remain in the Son, and in the Father. This is the promise which he promised us, even the life eternal." The preacher draws three questions from it: what is eternal life, where can it be found, and how do we begin to live it.

Message Outline

1. An Ancient Question in a Changing World

• With the rise of artificial intelligence, two extreme visions of the world appear.
• For some, the world is finally getting closer to the hoped-for ideal: every problem will be solved, diseases will be healed, and it will not even be necessary to work anymore.
• For others, new machines will reshape the world, and not for the better. Fear of losing a job, worry about the future of children, and doubt about the life one has built then arise.
• No one knows what the future will hold. Yet the preacher asks everyone the question: what is a good life? A beautiful life? A life worth living?
• Ecclesiastes 3:11 says that God "has also set eternity in their hearts." God has placed in us a heart that seeks this life.
• Neither our efforts nor the progress of science and technology can produce this life. No technique, no strategy can fill this desire: only God can.
• God did not give us this desire to torment us. Through it, he leads us to seek the source of life, the authentic life that he alone can give.

2. Eternal Life Is a Relationship That Never Ends

• No biblical author insists on eternal life as much as John. According to the preacher, more than half of the occurrences of the expression are found in his writings.
• Where the other Gospels speak of entering the kingdom of God, John speaks of having eternal life.
• Eternal life does not simply mean living forever. In the church, we sometimes think that it begins after death. John, however, speaks of a life that we can taste right now, and that lasts forever.
• Fundamentally, eternal life is a relationship: a relationship with the eternal God that never ceases. "This is eternal life, that they should know you, the only true God, and him whom you sent, Jesus Christ" (John 17:3).
• Our human relationships are temporary and limited. Sooner or later, they break or are severed. But God is eternal, and the relationship with him is of a different nature.
• When God created Adam and Eve, he created them to live with him in an endless relationship of love. This communion of love touched every aspect of their lives: from it flowed the harmony between them and with nature. With no sin and no death, nothing broke this relationship.

3. A Broken Relationship and a Thirst Nothing Can Quench

• Because of their sin, the relationship with the eternal God was broken.
• With it, the harmony between Adam and Eve and the harmony between humanity and creation were lost. Human beings became inhabitants of a broken world.
• We live surrounded by death, with a thirst that is never satisfied. Our life has become an effort to fill this void.
• We try to fill it with work, with a romantic relationship, with wealth, status or possessions.
• "In the end, this thirst is a thirst for God. It is a thirst that only God can quench."
• When John speaks of eternal life, he is really speaking of the restoration of the relationship with God. This restored relationship of love touches every area of our lives, now and for eternity: knowing God and being known by him.

4. Eternal Life Is Found in Jesus Christ

• Where can eternal life be found? 1 John 5:11-13 answers: "This is the testimony: that God gave to us eternal life, and this life is in his Son. He who has the Son has the life. He who doesn't have God's Son doesn't have the life."
• "John's answer is very clear: eternal life is in the Son of God, Jesus Christ."
• The letter is addressed to churches that had just gone through great confusion and division. False teachers there were teaching that believing in Jesus was not necessary for eternal life, that one could have a relationship with God without Jesus.
• Through these false doctrines, they sought to draw people away from the church.
• John answers them in 1 John 2:22-23: "Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. Whoever denies the Son doesn't have the Father. He who confesses the Son has the Father also."
• The promise of eternal life with God the Father is only possible through the relationship with Jesus Christ. To reject Jesus is to reject God. To know Jesus is to know God. And to know God is to have eternal life.

5. Let the Gospel Remain in You

• How do we begin to live eternal life? By letting the message of the Gospel remain in our hearts (1 John 2:24-25).
• According to commentators, what these believers had heard from the beginning is the Gospel that they had heard and believed.
• The Gospel is the news that God has loved us deeply, we who are sinners, and that he gave his Son to death in our place. Jesus bore the punishment on the cross for us. Because of this, instead of the judgment we deserved, we can receive grace and forgiveness. Through faith in Jesus, the relationship with God is restored.
• The Greek word translated "remain" literally means to dwell, to make a place one's home. We remain in Christ and live the promised eternal life by welcoming the Gospel and letting it dwell in us. "Does the Gospel dwell in you?"
• The image of the key: when coming home, the preacher always puts his keys in a small tray at the entrance. Once inside the house, he no longer needs them.
• Christians run the risk of treating the Gospel the same way: useful for entering into a relationship with God, then left behind, as if the ongoing relationship with Jesus no longer needed it.
• This is not the Christian life that John describes. He says: go back to what you received at the beginning. The Christian life is constantly shaped by the Gospel.
• Deepening your relationship with Jesus does not mean moving beyond the Gospel. This relationship always rests on the life, death and resurrection of Jesus. "To grow as a Christian, I must go ever deeper into the Gospel."

6. The Wood Stove at the Center of the House

• At the time when the preacher and his wife lived in Nagoya, a couple from the church, friends of theirs, had built a log house outside the city.
• The husband had ordered the materials on the Internet, from Europe. When they arrived, friends and neighbors came to help with the assembly, a bit like an IKEA piece of furniture, but in a giant version.
• The house was designed around a wood stove placed at its center. A single stove heated the whole house. In the dead of winter, it was very warm when you walked in.
• The owner explained that on cold nights, everyone slept with their bedroom door open: the heat spread this way into every room. When it got too hot, you closed the door a little; when you wanted to warm up, you opened it.
• "Letting the Gospel remain in us is like placing that wood stove at the center of the house." Reflecting on the Gospel, putting it into practice, seeking what it means for us: this is how its warmth spreads into every area of our lives.
• Is there a cold room in your life, with a door that stays closed? With the people at church, with the Bible open, the room may be warm. But at home, in your relationship with your family? At work? And in your own thoughts, inside you?

7. Opening the Cold Rooms to the Gospel

• Eternal life is a relationship with God, and this relationship transforms every area of life. It begins now and lasts forever.
• This change happens when we taste eternal life and the Gospel remains in our hearts.
• The preacher's call: if there is a closed room this morning, let us open it to the Gospel, and enjoy the eternal life made possible by Jesus Christ.
• In his prayer, he acknowledges that we try to quench our thirst in many ways, when there is only one way: the relationship with Jesus Christ, the Son of God.
• The time of prayer that follows invites everyone to name their cold room: the relationship with a spouse, the relationship between parents and children, relationships at work. Rather than trying to get through it by our own strength, the point is to open this room to Jesus so that he spreads the warmth of his love there.
• Those who have not yet welcomed Jesus are invited to begin there: to welcome him into their hearts.
• The final prayer sums it up: a communion with the eternal God that nothing breaks, not even death, and that has already begun.

Key Takeaways

• God has set eternity in our hearts. Neither technology nor our efforts can fill this desire: only God can.
• Eternal life is not only a life after death. It is a relationship with God that begins now and never ends.
• Our thirst, which we try to soothe with work, love, wealth or status, is at bottom a thirst for God.
• Eternal life is in the Son: to know Jesus is to know God.
• The Gospel is not a key that you set down once you are inside. It is the stove at the center of the house, whose warmth must reach every room.

Personal Application

1. In the face of the world's rapid changes, how would you answer today the question: what is a good life?
2. What are you trying to fill your inner thirst with: your work, a relationship, money, recognition?
3. Do you think of eternal life as something that will come later, or as a relationship with God that you can live starting today?
4. Have you "left the Gospel in the tray at the entrance"? How can you return to it this week, meditate on it and put it into practice?
5. What is your cold room: your marriage, your relationship with your children or your parents, your work, your thoughts? Are you ready to open it to Jesus?

Frequently Asked Questions

What is eternal life according to the apostle John?

For Jesse Rose, eternal life is not just a life that lasts forever, nor a life that would begin after death. It is a relationship that never ends with the eternal God: "This is eternal life, that they should know you, the only true God, and him whom you sent, Jesus Christ" (John 17:3). It can be tasted right now and lasts forever.

Where can eternal life be found?

John's answer is very clear: eternal life is in the Son of God, Jesus Christ (1 John 5:11-13). Faced with false teachers who taught that one could be in a relationship with God without Jesus, John affirms that to reject Jesus is to reject God, and that to know Jesus is to know God.

What does "remain" mean in 1 John 2:24?

According to the preacher, the Greek word translated "remain" literally means to dwell, to make a place one's home. What believers heard from the beginning is the Gospel. To let it remain in you is to welcome it and let it dwell at the center of your life, instead of setting it aside like a key once you have gone through the door.
