One man-centered cult teaches people "to turn their will and their lives over to a power greater than themselves.".
First of all, man is dead in his trespasses, and needs life, He needs more than rules and regulations., He needs to know that the Ruler is living within Him and granting Him life:
"The thief cometh not, but for to steal, and to kill, and to destroy: I am come that they might have life, and that they might have it more abundantly." (John 10: 10)
"But God, who is rich in mercy, for his great love wherewith he loved us, 5Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;) 6And hath raised usup together, and made us sit together in heavenly places in Christ Jesus." (Ephesians 2: 4-6)
We were taken from dead in our trespasses to alive and seated with Christ Jesus, made kings and priests forever (1 Peter 2: 9)
There can be no discussion, then, about anyone turning their life over to God, or to some "higher power".
We need life, and Jesus grants us His life:
"I am crucified with Christ: nevertheless I live; yet not I, but Christ liveth in me: and the life which I now live in the flesh I live by the faith of the Son of God, who loved me, and gave himself for me. 21I do not frustrate the grace of God: for if righteousness comeby the law, then Christ is dead in vain." (Galatians 2: 20-21)
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. 2Set your affection on things above, not on things on the earth. 3For ye are dead, and your life is hid with Christ in God. 4When Christ,who is our life, shall appear, then shall ye also appear with him in glory." (Colossians 3: 1-4)
So, Jesus gives us His life - not the other way around.
As for the will to do something or anything - Jesus gives us that, too!
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God. 2Set your affection on things above, not on things on the earth. 3For ye are dead, and your life is hid with Christ in God. 4When Christ,who is our life, shall appear, then shall ye also appear with him in glory." (John 16: 13)
"For it is God which worketh in you both to will and to do of his good pleasure." (Philippians 2:13)
"But ye have an unction from the Holy One, and ye know all things. " (1 John 2: 20)
So, let's give up this nonsense that we have to turn over something to God, for we have nothing to turn over to Him. He grants us all things!
