1. Worldly Christians (1-4)
Worldly Christians are Christians who need to grow. Paul calls them infants. They do not see things from God's point of view, but see everything from a human point of view. So they compete with others; sometimes they are proud, and sometimes, jealous. They follow human leaders instead of growing in Christ. We must grow up in Christ until we become spiritual men and women. Then we can please God and be useful to him. And we will have joy.
2. God's fellow workers (5-9)
God's servants are limited human beings, but God works through them. They cannot make another person grow spiritually. They cannot even make themselves grow. God alone gives life, and God makes us grow. God's servants only plant seeds, then water them with prayer and love and the word of God. Both the one who plants and the one who waters is a fellow worker with God. Their purpose is the same.
Application: Lord, thank you for using your servants to lead me to Jesus and to help me grow. Help me to grow in Christ until I can be a spiritual person and fruitful servant of God.
One Word: Grow up in Christ
