A SERVANT’S HEART. Serving Faithfully While God Gives the Increase. 1 Corinthians 3:1–15 KJV In 1 Corinthians 3:5–15, Paul teaches that Christian service is not about making celebrities out of servants. Paul planted, Apollos watered, but God gave the increase. The field teaches us to be faithful, the building teaches us to be careful, and the fire teaches us to live for eternity. Jesus Christ is the only foundation, and one day every believer’s work will be examined. Our responsibility is to plant, water, build, and faithfully serve. God gives the increase, and one day God gives the reward.
