First John 1:3 says that the apostle John is passing on what he personally saw and heard of Jesus so that his readers can share in the same close relationship he has. That relationship, he says, is shared with the Father and with his Son, Jesus Christ. The writer is John, traditionally identified as the apostle, and he is writing to a community of Christians who need to be drawn back into the truth about Jesus.
That which we have seen and heard we declare to you, that you also may have fellowship with us. Yes, and our fellowship is with the Father, and with his Son, Jesus Christ.

What 1 John 1:3 Means
The verse begins with testimony. “That which we have seen and heard” points to first-hand experience of Jesus, not a theory or a borrowed tradition. John is saying, in effect, “We were there, we know him, and we are telling you what we know.” Declaring it is an act of witness, meant to be passed on to others.
The purpose clause follows: “that you also may have fellowship with us.” The word translated fellowship carries the idea of shared life, partnership, and common participation. John wants his readers to enter into the same bond of trust and communion that he and the other apostles enjoy, not merely to hold the same opinions about Jesus.
The final sentence names the source of that fellowship. It is “with the Father, and with his Son, Jesus Christ.” The verse does not promise a vague spiritual warmth. It places the relationship at the center of the Trinity’s life, so that belonging to the church means belonging to God. It also does not promise that every reader will automatically feel close to God; it describes the relationship the message is meant to open up, which is received through faith and kept through obedience.
The Context of 1 John 1:3
The letter of 1 John is not signed by name, but the early church consistently connected it with the apostle John, who had walked with Jesus during his ministry. Its tone is pastoral and personal, written to believers who were facing teachers who denied that Jesus had truly come in the flesh and who were drawing people away from the community. The letter’s main concern is to test what is true and to strengthen the bond between believers.
The verses just before this one, in 1 John 1:1-2, explain why the testimony matters. John speaks of “the Word of life” that was from the beginning, which he heard, saw, and touched. Verse 3 is the conclusion of that thought: because the life was really revealed, the witness is reliable, and fellowship with God rests on that real history. The verses that follow, beginning in 1 John 1:5, shift from testimony to the character of God, who is light, so the fellowship being offered is also a call to walk in truth.

A Short Prayer From 1 John 1:3
Father, thank you that the good news was not kept hidden but was seen, heard, and shared by those who knew your Son. Help me to trust that testimony and to receive it as the foundation of my faith. Draw me into the fellowship you have made, with you and with your Son, Jesus Christ. Give me courage to speak honestly about what I have come to know of you, and make me a faithful member of the family of believers around me. Keep me walking in the light, so that my life reflects the relationship you are giving me. Amen.
