The law was given by Moses; grace and truth came by Jesus Christ. (John 1:17).
The law demands obedience; grace produces obedience. (Exod. 24:3; Titus 2:11, 12).
The law says, “Do and live”; grace says, “Live and do”. (Rom. 10:5; 1 Cor. 6:19, 20).
The law makes the offense abound; grace has over abounded. (Rom. 5:20).
The law condemns sinners; grace delivers them. (2 Cor. 3:9; Eph. 2:8).
The law is a schoolmaster; grace brings to the Father. (Gal. 3:25, 26).
The law was given to Israel; grace flows out to all. (Rom. 4:4; Titus 2:11).
The law was given in one language; grace goes out in all. (Exod. 32:15; Act 2:1-12).
The law addresses man in the flesh; grace creates anew. (1 Tim. 1:9; 2 Cor. 5:17).
“By the deeds of the law there shall no flesh be justified in His sight; for by the law is the knowledge of sin.” (Rom. 3:20).
“Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ.” (Gal. 2:16).
“Christ is the end of the law for righteousness to every one that believeth.” (Rom. 10:4).
“If righteousness come by the law, then Christ is dead in vain.” (Gal. 2:21).
The believer is
“not under the law, but under grace.” (Rom. 6:15).
“By grace are ye saved through faith,” (Eph. 2:8).
“But is not the law our rule of life when we are saved?” demand many. No; “for in Christ Jesus neither circumcision availeth anything nor uncircumcision, but a new creature (or, creation). And as many as walk according to this rule, peace be on them, and mercy,” (Gal 6:15, 16). “To me to live is Christ;” (not the law). “He that saith he abideth in Him, ought himself also so to walk, even as He walked.” (1 John 2:6.)
But we can fall from grace, can we not? Yes; but what does it mean? Falling from grace refers to a believer, who knows the grace of God, going back to law, not losing grace and falling into hell. (Gal. 5:4). Falling away refers to mere professors. (Heb. 6:6).
