1 John 1:1-4 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- 2 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- 3 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. 4 And we are writing these things so that your joy may be complete.
The beginning is referring to the beginning of Jesus’ earthly ministry. The “we” are the Apostles who were chosen to be with Jesus for the three years of His public ministry to the sinful people of Israel. Jesus was sent to earth to save His people from their sins (Matthew 1:21).
The Apostles give eyewitness testimony that Jesus was the word of life. Notice that they heard Jesus talk, they saw Him and touched Him. Jesus is the Way, the Truth and the Life (John 14:6). Jesus is God in the flesh, the second person of the Creator triune God, one God in three persons.
The Apostles purpose was to make known to the people of the world what they saw and heard so many people would be saved from their sins and have right relationships with other believers and with the Lord (Father, Son, and Holy Spirit). The Apostle wrote to the Church so the people’s joy would be complete. Believers in Christ have joy that is dependent on Jesus alone, not dependent upon other people. As believers learn the truth, they begin to know and experience this marvelous truth of joy that the world can’t take away. Paul experienced this joy even when experiencing sorrow (2 Corinthians 6:10).
May the Lord use the truth John proclaims to us to help us know and experience this joy the world cannot give and cannot take away.
