Do Not Forget The Heart, by McCheyne
Robert Murray McCheyne speaking at the ordination of Dn Edwards in the 1960's:
Mr. Edwards,... do not forget the inner man, the heart. The cavalry officer knows that his life depends upon his saber, so he keepsit clean. Every stains he wipes off with the greatest care.Mr. Edwards, you are God's chosen instrument. According to your purity, so shall be your success. It is not great talent; it is not great deas that God uses; it is great likeness to Jesus Christ. Mr. Edwards, a holy man is an awesome weapon in the hand of God.
