You see, we don’t go around preaching about ourselves. We preach that Jesus Christ is Lord, and we ourselves are your servants for Jesus’ sake. For God, who said, “Let there be light in the darkness,” has made this light shine in our hearts so we could know the glory of God that is seen in the face of Jesus Christ.
We now have this light shining in our hearts, but we ourselves are like fragile clay jars containing this great treasure. This makes it clear that our great power is from God, not from ourselves.
– 2 Corinthians 4:5-7
