“For if they which are of the law be heirs, faith is made void, and the promise made of none effect: Because the law worketh wrath…” (Rom. 4:14,15).
This should be self-evident to us all. If blessing is gained by the works of the Law, it is earned. This is why Gal. 3:18 says: “If the inheritance be of the law it is no more of promise, but God gave it to Abraham by promise.”
The Apostle Paul, God’s great apostle of grace, declares in Rom. 4:4,5:
“Now to him that worketh is the reward not reckoned of grace, but of debt. But to him that worketh not, but believeth on Him that justifieth the ungodly, his faith is counted for righteousness.”
But let’s go back to that phrase: “the law worketh wrath.” Many people somehow do not see this. Even some clergymen tell us that the Law was given to help us to be good. But God Himself says, “the law worketh wrath.” Every criminal knows this, and every sinner should know it. God certainly places strong emphasis upon it:
“Wherefore then serveth the law? It was added because of transgressions” (Gal. 3:19), “that every mouth may be stopped, and all the world may be brought in guilty before God” (Rom. 3:19). “Therefore 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).
If we come to God expecting eternal life because of our good works, are we not offering Him our terms, which He can never accept? He will never sell salvation at any price, and certainly not for a few paltry “good” works, when our lives are filled with failure and sin.
Our only hope? God has promised to give eternal life to those who trust in His Son. source
