I want to quote a prayer written by A.W. Tozer in his book The Pursuit of God.
"Father, I want to know Thee, but my coward heart fears to give up its toys. I cannot part with them without inward bleeding, and I do not try to hide from Thee the terror of the parting. I come trembling, but I do come. Please root from my heart all Those things which I have cherished so long and which have become a very part of my living self, so that Thou mayest enter and dwell there without a rival. Then shalt Thou make the place of Thy feet glorious. Then shall my heart have no need of the sun to shine in it, for Thyself will be the light of it, and there shall be no night there. In Jesus' name, Amen." (pg. 24)
