1 Corinthians 4:13-15

when we are slandered, we try to conciliate; we have become as the scum of the world, the dregs of all things, even until now. I do not write these things to shame you, but to admonish you as my beloved children. For if you were to have countless tutors in Christ, yet you would not have many fathers, for in Christ Jesus I became your father through the gospel.
