if you could 'stop that sinning' on your own, you wouldn't need Jesus. what God wants you to repent of is not all your 'transgressions of His laws'; but your desire to make your own decisions; He wants you to yield to His leading, so that He can guide you to intersect with the blessings He's already put in your future; and as you learn to perceive and follow His leading, you will transgress His laws less and less - effortlessly - as He will never lead you to transgress His laws. we aren't smart enough to know how to apply all of God's laws correctly in any given situation, only He is; we need to know what He has said to us in His written word so that we can recognize His leading in each situation, not so that we can strive to correctly apply and follow His laws according to our own strength and understanding. when you miss His leading, you step briefly into His mercy, receive His already-available forgiveness, and then step boldly back into His Throne room of grace for His next instructions
Psa 37:23 KJV
(23) The steps of a good man are ordered by the LORD: and he delighteth in his way.
Jer 10:23 KJV
(23) O LORD, I know that the way of man is not in himself: it is not in man that walketh to direct his steps.
Rom 8:1-14 KJV
(1) There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
(2) For the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death.
(3) For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
(4) That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit.
(5) For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
(6) For to be carnally minded is death; but to be spiritually minded is life and peace.
(7) Because the carnal mind is enmity against God: for it is not subject to the law of God, neither indeed can be.
(8) So then they that are in the flesh cannot please God.
(9) But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
(10) And if Christ be in you, the body is dead because of sin; but the Spirit is life because of righteousness.
(11) But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you.
(12) Therefore, brethren, we are debtors, not to the flesh, to live after the flesh.
(13) For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
(14) For as many as are led by the Spirit of God, they are the sons of God.
