The Apostle Paul also wrote to the Romans about being justified by grace through faith rather than through law-keeping…
I love God’s law with all my heart. But there is another power within me that is at war with my mind. This power makes me a slave to the sin that is still within me. Oh, what a miserable person I am! Who will free me from this life that is dominated by sin and death? Thank God! The answer is in Jesus Christ our Lord. So, you see how it is: In my mind I really want to obey God’s law, but because of my sinful nature I am a slave to sin. 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 law of Moses was unable to save us because of the weakness of our sinful nature. So, God did what the law could not do. He sent his own Son in a body likethe bodies we sinners have. And in that body God declared an end to sin’s control over us by giving his Son as a sacrifice for our sins. 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. 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. For the sinful nature is always hostile to God. It never did obey God’s laws, and it never will. That’s why those who are still under the control of theirsinful nature can never please God. But you are not controlled by your sinful nature. You are controlled by the Spirit if you have the Spirit of God living in you. (And remember that those who do not have the Spirit of Christ living in them do not belong to him at all.) And Christ lives within you, so even though your body will die because of sin, the Spirit gives you life because you have been made right with God. The Spirit of God, who raised Jesus from the dead, lives in you. And just as Godraised Christ Jesus from the dead, he will give life to your mortal bodies by this same Spirit living within you. 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 nature, you will live. Rom 7:22 – 8:13 (NLT)
Dear church family, the only way to get right and stay right with God is by the power of the Holy Spirit. We are saved by God and kept by God and not by our good works or acts of obedience. So, live by the Spirit.
