Romans 8:1 There is therefore now no condemnation for those who are in Christ Jesus. 2 For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death. 3 For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh, 4 in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.
8:1) condemnation: “judicial pronouncement upon a guilty person” When we repent of our sin and believe the gospel (question: Can you give me the Scripture references for “repent and believe the gospel?”) we are “in Christ”. When we are in Christ we have been pardoned from the curse of the Law (the penalty of sin) because Jesus paid the penalty of sin when He died on the cross (Galatians 3:13; John 19:30 – “it is finished” is better translated “it is paid”).
8:2) Fact: The law of the Spirit of life has set every believer free from the law of sin and death. (Note: The Holy Spirit was given to us when we believed the gospel to guarantee our inheritance of (1) all we need for life and godliness, (2) a new body and (3) the new heavens and earth – Ephesians 1:13-14, 18)
8:3a) Explanation of the fact: The law of sin and death refers to the Law. If a person does not keep all the Law then the person receives the curse of the Law, eternal torment, the second death (Galatians 3:10; Romans 8:23; Revelation 21:8). The Law is good and would benefit all who keep it, but the Law only instructs us what is good and does not empower to practice what it teaches. Thus, since we have all sinned (broken the Law), the Law condemns us. The Law is weak, because it can’t look past our sin or pay for our sin; it can only reveal our sin and put us to death.
Romans 8:3b) God is a just God and must punish sin. God is a loving God and wants to save us from the penalty and power of sin. To satisfy His justice, He sent His son to pay the penalty of sin on the cross and condemned sin in the flesh (“condemned” here means God judged sin to be done away with).
Romans 8:4) God sent His Son to be cursed (receive the penalty of sin) so the righteous requirement of the Law might be fulfilled in us. The righteous requirement of the Law was this: The Law must be fulfilled in every detail. Jesus pardoned all of our sins on the cross and we are left at the time of judgment with only the things we did that were righteous in accordance with the Law.
We who have trusted Jesus are free from condemnation. We are pardoned from the penalty of sin. God, because He loves us, will discipline us (believers) to turn us away from practicing sin so we can experience in our daily lives the peaceful fruit of righteousness (Hebrews 12:5-11). All of us who believe will be disciplined, but we will never be condemned. That is reason for rejoicing!
