1. Growth through constant exercise (5:11-6:3)

Christians should grow in spiritual wisdom and holiness to the level of being able to teach others. This comes through constant practice of obedience to God's word, which will help us become more and more discerning of good and evil. If we neglect this, we'll have to go back to the basics again. Faith is like a living seed; unless it grows, it dies.

2. warning (6:4-8)

If we hear God's word and know what we should do to please God, but deliberately reject it, then we are in danger of crucifying Jesus again and becoming thorn-bearers instead of fruit-bearers. No one can snatch us out of Jesus' hand (Jn 10:28); but we should be aware of the seriousness of falling away.
