Colossians 1:29

29 To get this done I toil and struggle, using the mighty strength which Christ supplies and which is at work in me.

Colossians 1:29 In-Context

27 God's plan is to make known his secret to his people, this rich and glorious secret which he has for all peoples. And the secret is that Christ is in you, which means that you will share in the glory of God.
28 So we preach Christ to everyone. With all possible wisdom we warn and teach them in order to bring each one into God's presence as a mature individual in union with Christ.
29 To get this done I toil and struggle, using the mighty strength which Christ supplies and which is at work in me.
