Jeremiah 45:3

So then, as I have this ministry because of God's mercy to me, I do not lose heart.

For this reason, as I have said, I do not lose courage, but even though my outward man is wasting away, my inward man is being renewed, day by day.

And let us not be weary in well-doing, for in due season we shall reap if we faint not.

But you, brothers, must not grow weary in well-doing.

Compare yourselves with him who endured such hostility against himself at the hands of sinners, lest you grow weary, fainting in your souls.

And let us not be weary in well-doing, for in due season we shall reap if we faint not.
