Here’s another great section of a letter John Newton wrote on March 13, 1781. (Reading hint: note the significance of these words near the end: “that fall within the line of our calling.”)
“I long aimed to be something. I now wish I was more heartily willing to be nothing. …A round 0 is by itself a thing of no value, and a million of them set in a row amount to no more than a single one; but place a significant figure before the row, and you may soon express a larger number than you can well conceive. Thus my wisdom is 0, my righteousness is 0, my strength is 0. But, put the wisdom, power, and grace of Jesus before them, let me be united to him, let his power rest upon my weakness, and be magnified in it, in this way I shall be something. Not in and of myself, but in and from him.”
“Thus the apostle speaks of being filled with all the fullness of God. What an amazing expression! Thus, so far as we die to self, Christ lives in us. He is the light by which we see, he is the life by which we live, he is the strength by which we walk, and by his immediate virtue and influence, all our works and fruits are produced.”
“We have no sufficiency in ourselves, but we have all-sufficiency in him, and at one and the same time we feel a conviction that we can do nothing, and [we also feel] an ability to do all things that fall with in the line of our calling. When I am weak, then I am strong.”
John Newton, Works VI, page 348.

Sounds like someone who has been touched by God’s amazing grace
