Doctrine of Grace: Hebrews 13: 9: For it is a good thing that the heart be established with grace…Read the verses surrounding verse 9 and define grace by the opposites revealed here. Man's teachings are varied but God's gospel of grace is one unchangeable word. The doctrines of men are foreign to the word of God; God's word of grace is one with his essential character. Man's teachings carry men about in the flesh; the doctrine of grace establishes the heart. Man's teachings are unprofitable; the doctrine of grace gives unsearchable riches. Man's doctrines teach salvation by every man's servitude; the grace of God, and the gift by grace, is by one man, Jesus Christ the same yesterday, and today and forever.
