1Co_3:5 Who then is Paul, and who is Apollos, but ministers by whom you believed, even as the Lord gave to every man?

Heb 13:7 Appreciate your pastoral leaders who gave you the Word of God. Take a good look at the way they live, and let their faithfulness instruct you, as well as their truthfulness. There should be a consistency that runs through us all.
