Colossians 1:23-25

if indeed you continue to advance in faith, assured of a firm foundation to grow upon. Never be shaken from the hope of the gospel you have believed in. And this is the glorious news I preach all over the world. I can even celebrate the sorrows I have experienced on your behalf; for as I join with you in your difficulties, it helps you to discover what lacks in your understanding of the sufferings Jesus Christ experienced for his body, the church. This is the very reason I’ve been made a minister by the authority of God and a servant to his body, so that in his detailed plan I would fully equip you with the Word of God.
