To be under grace means that sin cannot have dominion over us because grace in Christ frees us from the condemnation of perfect Law-obedience in Adam. This is through our Lord’s perfect Law-keeping life and atoning death for law-breakers. You really cannot understand the cross without understanding the Law. Under grace means that God grants us justification by faith alone in Jesus Christ through His perfect atonement for sin and the imputation of His perfect righteousness as a gift. It also means that the new birth writes God’s Law upon our hearts so that we delight in it again (Jeremiah 31:31-34, 32:40; Romans 7:22). This “grace in which we stand” throughout the Christian’s walk impels and empowers the forgiven sinner to love God and keep His commandments without fear of condemnation. Under grace, the believer no longer finds obedience to God’s Law a condemning burden, but a joyful privilege of the saved under grace (Romans 3:24, 5:2, 5:15, 5:21, 6:14-15). The Christian lives under grace according to God’s Law so that sin no longer has dominion over him. Although the Christian still commits sins against God’s commandments while under grace, the power of sin, which is the condemnation of the law, is broken. Sanctification, then, is the daily exercise of saving faith in Christ, redeemed by His blood and covered with His righteousness, by which justifying faith we seek to keep the Law of God under grace. That is why Jesus said: “if you love Me, you will keep My commandments.” Faith working through love to God is the evidence of being under grace. And such faith always works.
