Paul's Letter to the Galatians - Chapter 5 verses 16 to 18

(16)  This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
(17)  For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
(18)  But if ye be led of the Spirit, ye are not under the law.
