1. Those who follow their natural instincts (8-16)

Jude warns about ungodly people who live according to their instincts. They have no fear of God and no respect for anyone. They have no truth of God and no spiritual understanding; they grumble, find fault and sometimes flatter people for their own advantage. Cain was one such man. He judged God and became a restless wanderer. Another example was Balaam who tried to use his spiritual gifts for personal profit (Nu 24; 2Pe 2:15). Korah instigated a rebellion against God's servant Moses (Nu 26). Those who follow the desires of the sinful nature and not God's word are like clouds without rain, shepherds who only feed themselves; they are twice dead.

2. A call to persevere (17-23)

We must live by the Spirit, not by the flesh. We must build ourselves up in faith through prayer and obedience to God's word and keep ourselves in God's love. We must do our best to live as Jesus' people as we wait for his return.

Application: Lord, help me to live by the Spirit, not by the flesh.
One Word: Keep yourselves in God's love
