Final answer:
John had fellowship with God the Father and Jesus Christ according to 1 John 1:3. This establishes that Christians have a spiritual connection with God and Jesus, which is central to the community's faith and practice. John's eyewitness testimony helps strengthen the credibility of Christian communal beliefs.
Step-by-step explanation:
According to 1 John 1:3, John had fellowship with the Father and with his Son, Jesus Christ. This verse is a part of a letter written by John, one of Jesus' apostles, and it addresses the Christian community about the nature of God and the importance of fellowship in the Christian faith.
John emphasizes that this fellowship is not only amongst believers but is primarily shared with God the Father and Jesus Christ, indicating a close-knit, spiritual relationship that defines Christian communion.
The apostle's testimony about his experience with Jesus is meant to inspire and invite others into this spiritual fellowship, assuring them that this relationship is real and accessible.
By stating his firsthand experience, John establishes his credibility and underscores the importance of this spiritual connection in developing a robust Christian community. He conveys the message that through the love and sacrifice of Jesus, believers can be brought into a direct and intimate relationship with God.
It is this spiritual connection that allows believers to have communion with God, which is central to Christian teachings and practice. The Christian community, connected by this shared faith and divine relationship, is encouraged to strengthen its bonds with one another and with God, fulfilling the purpose of the teachings of Jesus as understood by His apostles like John.
