John places a high priority on the quality of Christian community by teaching that our fellowship and joy is rooted in what we believe about Jesus. For those that have experienced Christ by the power of the Holy Spirit, we can no longer live in darkness as slaves to sin. We are invited to bring our brokenness into the light where we can be cleansed from all unrighteousness. The basis of our salvation and our sanctification is the person of Jesus. He is the Christ. He is the Son of God. He has come in the flesh. Jesus’ incarnation is the central doctrine of Christian faith. We gather with other believers on the basis of this truth. John’s challenge to us is to discern truth and error as we seek to obey Jesus’ commands and live His values.
