THIS IS A MOST POWERFUL PRAYER! I would encourage you to print it out and pray through it often.
In the Name of Jesus I completely surrender myself to You, Heavenly Father, as a living sacrifice. I choose not to be conformed to this world, but choose to be transformed by the renewing of my mind, that I may prove what is the good and acceptable and perfect will of God. Father, I pray that You would show me Your will and enable me to walk in all the fullness of Your will for my life. I claim that Your power and Your anointing shall be upon me, and that when the enemy comes against me one way, the Holy Spirit will force him to flee from me seven different ways. I pray and believe that every trap the enemy sets for me will backfire on him, and work out for my good, which is for Your glory; for You said all things work together for the good, for those who love the Lord, who are called according to Your purpose. Satan, the blood of Jesus Christ is against you.
