The Law of Sin and The Law of The Mind
When the Holy Spirit regenerates and converts a sinner, He imparts to our minds and hearts a new, holy desire. This desire, however, is much more than merely to “be good.” It is a desire to glorify God and exalt Christ in all we think, say, and do. It is a desire to be and to do good but only in a way that honors God and shows forth the glory of His mercy, grace, love, and power in Christ.
Even though we have this desire from God, while in this life, it is an unfulfilled desire as to its perfection. It is a holy desire because by it we truly desire that which is holy in Christ. We still, however, have other desires within us that continually plague and contaminate our best efforts to glorify God and honor Christ. Paul called this the “law of sin” within him waging war against another law of his mind (Romans 7:20,23). The “law of sin” is a powerful active principle of sin. The “law of my mind” is a powerful active principle of grace. It is the work of the Holy Spirit within causing us to look to Christ, rest in Him and His finished work, and seek to be conformed to Him.
Paul summarized the whole matter in the following verses – “O wretched man that I am! who shall deliver me from the body of this death? I thank God through Jesus Christ our Lord. So then with the mind I myself serve the law of God; but with the flesh the law of sin. There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.”(Romans 7:24—8:1)
