"Desire the sincere milk of the word, that ye may grow thereby: if so be ye have tasted that the Lord is gracious" (1 Peter 2:2-3)
Before we can be filled with the Holy Spirit the desire to be filled must be all-consuming. It must be for the time the biggest thing in life, so acute, so intrusive as to crowd out everything else.
The degree of fullness in any life accords perfectly with the intensity of true desire. We have as much of God as we actually want. One great hindrance to the Spirit-filled life is the theology of complacency so widely accepted among gospel Christians today.
According to this view acute desire is an evidence of unbelief and proof of lack of knowledge of the Scriptures. A sufficient refutation of this position is afforded by the Word of God itself and by the fact that it always fails to produce real saintliness among those who hold it.
I have met Christians who have been wanting to be filled, in a vague sort of way, for many years. The reason they have not been filled with the Holy Spirit is because they have other things they want more.
