Galatians 5:16 “This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.”
“The Bible does not say, “Don’t walk in the flesh and you will be in the Spirit.” Rather, it clearly teaches the opposite. “Walk in the Spirit, and you will not fulfill the lusts of the flesh.” Notice the positive precedes the negative; ‘walk in’ comes before ‘not fulfill’. How many young Christians get hung up on this very point? They believe that they must conquer their flesh before they can walk in the Spirit. Consequently, they may spend years in futile efforts before realizing the walk of faith. The reality is that the only way for the flesh to be subdued is to draw from a power greater than our own innate human nature.
They wait for some vague time when they hope they will have reached a more satisfactory position in regard to the lusts of the flesh, and will feel more confident about attempting a walk in the Spirit. But that is all wrong way around. If we are to wait until we have, in some degree, mastered the lsts of the flesh before we venture to walk in the Spirit; if we are to wait until we feel that we can give some sort of security to ourselves and to God that we shall do a bit better in the future than we have done on the past, then we never will walk in the Spirit. For until we walk in dependence upon the Spirit we shall not, and cannot, overcome the lusts of the flesh.” – D. Tryon
“He who knows that awful power of the self-life within – its enmity with God, its carnality, its grieving, its quenching of the Spirit, its deadly blighting of all the blessed fruit of the Spirit, its fierce and desperate resisting of his hunger to enter into the full life of the Spirit – needs no other explanation of the lack of the fullness of the Spirit than the fullness of self.” – James H. McConkey
