It isn't enough to become a Christian and then stand around in a vacuum of knowledge without any information out of the Word of God and hope everything turns out right.
We have to be saturated in the Word of God on a day-by-day basis so that the Word of God implanted in the mind and the heart becomes the control vehicle by which the Spirit of God leads us as we live day by day.
And when we're filled with the Word of God, controlled by the Spirit of God, walk in obedience to that revealed will of God, we will not fulfill the lust of the flesh, but we will fulfill the law by loving each other
What does it mean to walk in the Spirit?
Walk is the idea of daily conduct, daily conduct, routine life pattern. And how do you walk in the Spirit? Very simply, where does the Spirit reveal His will? Where does the Spirit give us His direction? In the Word of God, right? I don't think walking in the Spirit is mystical or ethereal, I don't think it's some kind of heavenly thing, I don't think it's some kind of ecstatic emotional experience. Walking in the Spirit is very simple, it is walking in obedience to the mind and will of the Spirit of God. And that means to be saturated with the Word of God so that the Word of Christ dwells in you richly and that then, that word then becomes the control factor used by the Spirit of God to lead you into obedience
