Paul was confident that the Spirit of God lived in the Corinthians and commended them with his letter. In fact, he said to them, "you are our letter of commendation". His ministry was evidenced in their lives. His work was written on their hearts. They were being changed to be more obedient to Christ.
Are there people who you could write that are looking to you as their spiritual mentor? Is there anyone that would commend you to God with their life? As believers we should be constantly pouring our lives out so that others can know Jesus and grow in a greater understanding of Him. It is a challenge and a life worth living.
Consider helping others know and and obey Jesus today.
