The gospel of the grace of God takes the stain of memory from a worker, not by making him ignore the past, but by enabling him to see that God can make it of service in His work for God. "...unless we know the Cross of Christ as the power which takes the stinging stain out of memory and transforms it, we are of no use to others.

The gospel can never be preached by sinless lips, but only the lips of those who have been saved from sin by Atonement.

Angels cannot preach the gospel.... Oswald Chambers

"I do not count myself to have apprehended; but one thing I do, forgetting those things which are behind and reaching forward to those things which are ahead, I press toward the goal for the prize of the upward call of God in Christ Jesus.“ Philippians 3:13-14
