The first essential for the coming of the Holy Ghost into a heart today is that the heart should be cleansed from sin, for the Holy Spirit does not fill an unclean heart. What God has cleansed, He then fills. Finally, whom God fills, He uses. A holy life is the authentic sign of being filled with the Spirit.
Leonard RavenhillThe greatest miracle that God can do today is to take an unholy man out of an unholy world, and make that man holy and put him back into that unholy world and keep him holy in it.
