Romans 3:19-24

Now we know that whatever the law says it speaks to those who are under the law, so that every mouth may be stopped, and the whole world may be held accountable to God. For by works of the law no human being will be justified in his sight, since through the law comes knowledge of sin.

But now the righteousness of God has been manifested apart from the law, although the Law and the Prophets bear witness to it— the righteousness of God through faith in Jesus Christ for all who believe. For there is no distinction: for all have sinned and fall short of the glory of God, and are justified by his grace as a gift, through the redemption that is in Christ Jesus,

Romans 5:18-21

Therefore, as one trespass led to condemnation for all men, so one act of righteousness leads to justification and life for all men. For as by the one man's disobedience the many were made sinners, so by the one man's obedience the many will be made righteous. Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord.

Question: If God’s law is holy and good, yet cannot itself make us holy, how then do we truly obey it?

Answer: We die to the law’s demands and belong to Christ, who conquered sin and grants the Holy Spirit. Freed from guilt and empowered by grace, we now delight to keep God’s commands—not to earn His favor, but out of love for the Redeemer who set us free.

Romans 7:24–25a (ESV)
“Wretched man that I am! Who will deliver me from this body of death? Thanks be to God through Jesus Christ our Lord!”
