Walk by the Spirit, and you will not gratify the desires of the flesh.

Your body is not evil in itself. The flesh is the ego which feels an emptiness and uses the resources in its own power to try to fill it. The Flesh is the "I" who tries to satisfy you with anything but God's mercy. (Galatians 5:24), "Those who belong to Christ Jesus must crucify the flesh with its passions and desires. Walk by the Spirit by resting in the promises of God. The Spirit reigns over the flesh in your life when you live by faith in the Son of God who loved you and gave himself for you and now is working everything together for your good. Stop trying to fill the emptiness of your life with a hundred pieces of the world, and put your soul at rest in God. The Spirit will work the miracle of renewal in your life when you start meditating on his unspeakable promises day and night and resting in them. (Romans 15:13, 2 Peter 1:4, and Isaiah 64:4.)
Walk by the Spirit, and you will not gratify the desires of the flesh. You will have victory over temptation and know the guidance of the Lord if you keep your heart happy in God by resting in his promises.
