But by God's grace I am what I am, and the grace that he gave me was not without effect. On the contrary, I have worked harder than any of the other apostles, although it was not really my own doing, but God's grace working with me.

So then, my dear friends, stand firm and steady. Keep busy always in your work for the Lord, since you know that nothing you do in the Lord's service is ever useless.

So let us not become tired of doing good; for if we do not give up, the time will come when we will reap the harvest.

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