Everyone who has this hope set on him purifies himself, even as he is pure.

 (i) Frequently the Bible uses the word seed to mean a man's family and descendants. Abraham and his seed are to keep the covenant of God ( Genesis 17:9). God made his promise to Abraham and to his seed for ever ( Luke 1:55). The Jews claim to be Abraham's seed ( John 8:33; John 8:37). In Galatians 3:1-29, Paul speaks about Abraham's seed ( Galatians 3:16; Galatians 3:29). If we take seed in that sense here, we need to take him as referring to God and then we get very good sense. "Anyone who has been born of God does not sin, because God's family constantly abide in God." God's family live so near to God that they may be said to abide in him. The man who lives like that has a strong defence against sin.
