23 for all have sinned and fall short of the glory of God, 24 being justified freely by His grace through the redemption that is in Christ Jesus, 25 whom God set forth as a propitiation by His blood, through faith, to demonstrate His righteousness, because in His forbearance God had passed over the sins that were previously committed, (Romans 3:23–25, NKJV)
All of us have sinned and are worthy of death (Rom. 6:23). None of us could justify ourselves before God. We could not remove our sins by our own power, because we were spiritually dead (Eph. 2:1). Separated from God by our sins, we were under divine wrath (Rom. 1:18). We needed grace to save us. The kindness and love of God appeared to the world “through the redemption that is in Christ Jesus” (v. 24). God acted to save us. He set forth Christ Jesus “as a propitiation by His blood” (v. 25). A propitiation is the means of appeasing wrath, that which atones for sins. The death of Jesus atones for sins, it is the means of removing God’s wrath and replacing it with mercy (1 John 2:2). The atoning sacrifice of Jesus is “through faith” – not through the law (Rom. 3:20; Gal. 2:16). The gospel has the power to save you by producing faith in your heart (Rom. 1:16-17; 10:17). When that happens, your faith prompts you to confess your faith in Jesus, to repent of your sins, and to be baptized to be saved (Mk. 16:15-16; Acts 2:37-38). This is salvation “by grace, through faith” (Eph. 2:8).
