"So now there is no condemnation for those who belong to Christ Jesus. And because you belong to Him, the power of the life-giving Spirit has freed you from the power of sin that leads to death."
The Spirit in us has freed us from sin, it has showed us and will continue to show us what is wrong and right so we can have help in our decision making. We have a Spirit in us that loves us and guides us, we are not on our own thanks to God and His love for us. Verse 4 says, "He did this so that the just requirement of the law would be fully satisfied for us, who no longer follow our sinful nature but instead follow the Spirit." We must make the effort to know what the Spirit is saying. He is not confusing, but He will not force us to do what is right, He will only comfort, guide and prompt us.
Paul shares in verse 5-6, "Those who are dominated by the sinful nature think about sinful things, but those who are controlled by the Holy Spirit think about things that please the Spirit. So letting your sinful nature control your mind leads to death. But letting the Spirit control your mind leads to life and peace." We can't fight what's in us if we continue to feed it. That happens by studying God's word, praying to God always and stopping to listen to what the Spirit is showing us before we react out of emotion.
Our desire to know what is best for us is strong because the world teaches us that we control our own destiny. But I say, when we learn surrender and submission then we truly open our heart to let God change it. When we begin to change, we see how much the Spirit of God knows what is best for us (even if it doesn't seem that way.) Jesus talked about blaspheming the Holy Spirit in Mark chapter 3 verses 28-29 which says, "I tell you the truth, all sin and blasphemy can be forgiven, but anyone who blasphemes the Holy Spirit will never be forgiven. This is a sin with eternal consequences." As we grow and walk by the Spirit we show that something is more important than our desires and we take 2nd chair to what God has shown us and given us, and our desires become ones that want to please Him.
I want to finish with what Paul says in Romans chapter 8 verses 12-14, "Therefore dear brothers and sisters, you have no obligation to do what your sinful nature urges you to do. For if you live by its dictates, you will die. But if through the power of the Spirit you put to death the deeds of your sinful mature, you will live. For all who are lead by the Spirit of God are children of God." Amen
