If you have been born again, if you are saved, if you are in Christ Jesus, then you are free from the penalty of sin! This is so significant because the Bible makes it clear that sin is a destructive and deadly force. Sin will wreak havoc in your life.
Even though as mature believers experience consistent victory over sin, we still struggle daily against the flesh and occasionally lose the battle. So we must understand how to deal with guilt and how to overcome temptation. When we do sin as Christians, the enemy comes in to stir up doubts about our salvation: “How do you know that your sins are all forgiven? True Christians don’t do what you just did! You’re hopeless! You might as well admit your hypocrisy in claiming to be a Christian and quit trying to be holy.” Remember that Satan is a liar, he is called the father of lies.
We are to do this:
THEREFORE THEN, since we are surrounded by so great a cloud of witnesses [who have borne testimony to the Truth], let us strip off and throw aside every encumbrance (unnecessary weight) and that sin which so readily (deftly and cleverly) clings to and entangles us, and let us run with patient endurance and steady and active persistence the appointed course of the race that is set before us
Hebrews 12:1
On top of that, Paul directs us to these opening verses in Romans 8:
THEREFORE, [there is] now no condemnation (no adjudging guilty of wrong) for those who are in Christ Jesus, who live [and] walk not after the dictates of the flesh, but after the dictates of the Spirit. [John 3:18.]
2 For the law of the Spirit of life [which is] in Christ Jesus [the law of our new being] has freed me from the law of sin and of death.
3 For God has done what the Law could not do, [its power] being weakened by the flesh [the entire nature of man without the Holy Spirit]. Sending His own Son in the guise of sinful flesh and as an offering for sin, [God] condemned sin in the flesh [subdued, overcame, deprived it of its power over all who accept that sacrifice], [Lev. 7:37.]
4 So that the righteous and just requirement of the Law might be fully met in us who live and move not in the ways of the flesh but in the ways of the Spirit [our lives governed not by the standards and according to the dictates of the flesh, but controlled by the Holy Spirit].
Romans 8:1–4.
God has graciously set free from sin’s penalty and power all who are in Christ Jesus.
