I must do the work of the one who sent me while it is day. Night is approaching, when no one can work.

Therefore, my dear brothers, be steadfast, unmovable, always excelling in the work of the Lord, because you know that the work that you do for the Lord isn't wasted.

And so death is at work in us, but life is at work in you.

I have sent you to harvest what you have not worked for. Others have worked, and you have adopted their work as your own."
