“If we are willing to put ourselves into God’s hands, then God is willing to use us.  But there are two conditions: Obedience and purity.

Obedience in everything, even in the least, surrendering up our wills and taking the will of God.

And the next step is purity.  God wants pure vessels for His service, clean channels through which to pour forth His grace.  He wants purity in the very centre of the soul, and unless God can have a pure vessel, purified by the fire of the Spirit, He cannot use that vessel.

He is asking you now if you will let Him cleanse away part of your very life.  God must have a clean vessel He can use.”
