3:18 condemned already. See also John 3:36. The world is under universal condemnation because of universal sin. There can be no deliverance from this fate except to receive the gift of salvation from the one who was “made…sin for us…that we might be made the righteousness of God in Him” (II Corinthians 5:21). On that basis—and that alone—can we be saved from this condemnation (Romans 8:3; Galatians 3:13). We must look unto Him if we are to be saved (Isaiah 45:22).

3:18 only begotten. See on John 1:18 for the vital importance of believing in the “only begotten” Son of God. His unique Sonship required the virgin birth, and was proved by the resurrection (Psalm 2:7; Acts 13:33; Romans 1:4; John 5:26).
