Proverbs 30:5-6, which Neville uses as the licence for the entire method and as a prohibition in the same breath. Every word of God proves true - so any promise in scripture may be treated as a law that will perform, and the one he reaches for is Mark 11:24, whatever you desire when you pray, believe you have received it and you will. Then the second half: do not change his words, do not add to them, do not alter them, lest you be rebuked by him and found a liar. He uses the prohibition to refuse every moral qualification the churches attach to the promise - it does not say let the priesthoods of the world tell you that it's good for you, it does not say society tells you whether you should want to transcend your present level; it says whatever you desire, with no restraint on the desire. His own proof is the discharge from the army (M818): his word told me to do exactly what I did, and I proved the word of God. About five lectures. The prohibition on altering scripture also appears inside M764, where it concerns the word ought and the sin against the Holy Spirit; this motif carries the positive half, that the word performs.
