What an exceeding joy is this! He who has purified us with the blood of Jesus will also cleanse us by the water of the Holy Spirit. God hath said it, and so it must be, “Ye shall be clean.” Lord, we feel and mourn our uncleanness, and it is cheering to be assured by Thine own mouth that we shall be clean. Oh, that Thou wouldst make a speedy work of it!
He will deliver us from our worst sins. The uprisings of unbelief and the deceitful lusts which war against the soul, the vile thoughts of pride, and the suggestions of Satan to blaspheme the sacred name-all these shall be so purged away as never to return.
He will also cleanse us from all our idols, whether of gold or of clay: our impure loves and our excessive love of that which in itself is pure. That which we have idolized shall either be broken from us or we shall be broken off from it.
It is God who speaks of what He Himself will do. Therefore is this word established and sure, and we may boldly look for that which it guarantees to us. Cleansing is a covenant blessing, and the covenant is ordered in all things and sure.
