by John Piper
I will give them a heart to know Me, for I am the Lord; and they will be My people, and I will be their God, for they will return to Me with their whole heart.
So then, my beloved, just as you have always obeyed, not as in my presence only, but now much more in my absence, work out your salvation with fear and trembling; for it is God who is at work in you, both to will and to work for His good pleasure.
But by the grace of God I am what I am, and His grace toward me did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me.
1 Corinthians 15:10
