God has given me the responsibility of serving his church by proclaiming his entire message to you. This message was kept secret for centuries and generations past, but now it has been revealed to God’s people. For God wanted them to know that the riches and glory of Christ are for you Gentiles, too. And this is the secret: Christ lives in you. This gives you assurance of sharing his glory.
So we tell others about Christ, warning everyone and teaching everyone with all the wisdom God has given us. We want to present them to God, perfect in their relationship to Christ.
