21 So I find it to be a law that when I want to do right, evil lies close at hand.
22 For I delight in the law of God, in my inner being,
23 but I see in my members another law waging war against the law of my mind and making me captive to the law of sin that dwells in my members. – Romans 7:21-23
The war that rages in our mind, heart and body. In our mind we agree that the law is good we delight in the word of God. But then we rationalise “everyone does it, it’s not wrong” and excuse ourselves. In our heart we have an emotional desire to follow Jesus but another desire wells up inside us To do our own thing, to be our own boss, do what we want, go our own way – what ever that may consist of. Our bodies have needs and desires be it food, comfort or closeness that we can allow God to fulfil or we can fulfil our own desires often resulting in sin. When we want to do right our evil hearts desires often win. Paul talks about being captive to the law is sin that dwells within us. That phrase had led some scholars (Moo 2014) to suggest that in this passage on the dilemma of flesh waring against the Spirit Paul is describing the experience of a Jew trying to live under the law rather than a born again Christians experience because when you are born again you are not captive to sin but made free.
23 Now before faith came, we were held captive under the law, imprisoned until the coming faith would be revealed.
24 So then, the law was our guardian until Christ came, in order that we might be justified by faith.
25 But now that faith has come, we are no longer under a guardian,
26 for in Christ Jesus you are all sons of God, through faith. – Galatians 3:23-26
5 We destroy arguments and every lofty opinion raised against the knowledge of God, and take every thought captive to obey Christ,
6 being ready to punish every disobedience, when your obedience is complete. – 2 Corinthians 10:5-6
But the most important thing here to consider is Paul does not reject the law. The law is not evil but good. God gave us the law for a purpose. For us to learn that we can not live up to His righteousness in our own strength. The law is our guardian or as the NKJV translates it, the law is our tutor:
Therefore the law was our tutor to bring us to Christ, that we might be justified by faith. – Galatians 3:24 (NKJV)
We learn from the law. It is not abolished but fulfilled by Christ.
