Introduction of 1 John

First John was written by the apostle John late in the first century (around AD 85–95). Addressing churches troubled by emerging false teachings about Jesus, John emphasizes the reality of the incarnation and the importance of love. The letter tests genuine faith through right belief, obedience, and sacrificial love for others. Its warm yet urgent tone circles around the themes of light, truth, and fellowship with God and His people. It leaves readers asking: do we truly know and abide in the God who is love?
