O unhappy and pitiable and wretched man that I am! Who will release and deliver me from [the shackles of] this body of death? O thank God! [He will!] through Jesus Christ (the Anointed One) our Lord! So then indeed I, of myself with the mind and heart, serve the Law of God, but with the flesh the law of sin. Romans 7:24-25 AMPC http://bible.com/8/rom.7.24-25.AMPC But For the law of the Spirit of life [which is] in Christ Jesus [the law of our new being] has freed me from the law of sin and of death. For God has done what the Law could not do, [its power] being weakened by the flesh [the entire nature of man without the Holy Spirit]. Sending His own Son in the guise of sinful flesh and as an offering for sin, [God] condemned sin in the flesh [subdued, overcame, deprived it of its power over all who accept that sacrifice], [Lev. 7:37.] So that the righteous and just requirement of the Law might be fully met in us who live and move not in the ways of the flesh but in the ways of the Spirit [our lives governed not by the standards and according to the dictates of the flesh, but controlled by the Holy Spirit]. Romans 8:2-4 AMPC http://bible.com/8/rom.8.2-4.AMPC We with our hearts (inner man) and minds do (can) make the choice to serve the law of the Spirit, our flesh serves the law of sin. But the law of the Spirit of life [which is] in Christ Jesus has freed me from the law of sin. So now we can renew our minds with the law of the Spirit and train our flesh to submit to it. For we are no longer bound to sin if Jesus is our Lord. For Jesus defeated the power of sin on the cross. If we accept God's sacrifice of His Son, taking our place as a payment for our sin, the requirement of the law for righteousness and being just is fulfilled by our making the choice to live and move in the ways of the Spirit. We choose to make our fleshly nature submit to the ways of the Spirit, to allow the Holy Spirit to be in control. This is our sacrifice, our part in suffering for the cross.... denying the flesh to walk in the worlds evil sinful ways. For those who are according to the flesh and are controlled by its unholy desires set their minds on and pursue those things which gratify the flesh, but those who are according to the Spirit and are controlled by the desires of the Spirit set their minds on and seek those things which gratify the [Holy] Spirit. Romans 8:5 AMPC http://bible.com/8/rom.8.5.AMPC This person seeks continually to please the Holy Spirit. Now the mind of the flesh [which is sense and reason without the Holy Spirit] is death [death that comprises all the miseries arising from sin, both here and hereafter]. But the mind of the [Holy] Spirit is life and [soul] peace [both now and forever]. Romans 8:6 AMPC http://bible.com/8/rom.8.6.AMPC This is the reason why we need to take captive all our thoughts according to 2 Corinthians 10: For though we walk (live) in the flesh, we are not carrying on our warfare according to the flesh and using mere human weapons. For the weapons of our warfare are not physical [weapons of flesh and blood], but they are mighty before God for the overthrow and destruction of strongholds, [Inasmuch as we] refute arguments and theories and reasonings and every proud and lofty thing that sets itself up against the [true] knowledge of God; and we lead every thought and purpose away captive into the obedience of Christ (the Messiah, the Anointed One), 2 Corinthians 10:3-5 AMPC http://bible.com/8/2co.10.3-5.AMPC Blessings to you all!
