John opens up this letter by stating that what he is about to write comes from his personal relationship with Jesus, the Savior of the world. He talked with Jesus, walked with him, and shared many moments with Him. Today, we know Jesus in a similar way. Perhaps, we do not physically walk with him or see him as John and the other apostles did. But the same Holy Spirit that was with John lives in us today as we walk in faith in Jesus. In verse four, he adds that the purpose of writing is that our joy may be complete. May that be true in our lives today. May we experience the joy that comes from having a real relationship with Jesus Christ.
"That which was from the beginning, which we have heard, which we have seen with our eyes, which we looked upon and have touched with our hands, concerning the word of life— the life was made manifest, and we have seen it, and testify to it and proclaim to you the eternal life, which was with the Father and was made manifest to us— that which we have seen and heard we proclaim also to you, so that you too may have fellowship with us; and indeed our fellowship is with the Father and with his Son Jesus Christ. And we are writing these things so that our joy may be complete."
1 John 1:5-7
