Living in the Spirit is the constant struggle that every Christian will have until we go to Christ or Christ comes to us. Let us not believe in the idea that this is something easy, because the flesh will make us various offers and that will keep us busy in a fight between the flesh and the Spirit.
The apostle Paul said:
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.
