1 John 2:24

Christians should not reject the truth that they believed that resulted in their salvation (cf. the warning passages in Hebrews). Such faithfulness enables us to continue to abide in fellowship with God. John used "abide" in the same sense in which Jesus did in the Upper Room Discourse. Abiding refers to an intimate relationship with God determined by the extent to which we walk in the light of God’s will that we have. Abiding, fellowship, and knowing God refer to the same thing, and we experience them by degrees rather than either completely or not at all (John 15:1-8). John’s insistence that his readers really did know God and His truth would have strengthened them to resist the false teachers (1 John 2:12-14; 1 John 2:21).
