God’s holiness has been consistent from the Old Testament to the New, calling His people to be holy as He is holy (Lev. 11:44–45; 1 Pet. 1:15–16). Yet man’s sinful heart makes it impossible to walk in righteousness without God’s grace (Gen. 6:5; Jer. 17:9; Rom. 8:7–9). Through Christ, God’s grace gives us a new heart and His Spirit to empower holy living (Ezek. 36:26–27; Jer. 31:33). Grace is not a license to sin, but the divine power that enables us to live in obedience and reverence before a holy God (Heb. 10:26–31).
