A quote by Charles Finney

Ye who have submitted to God feel the need of salvation deep and thorough. Sometimes, your experience compels you to exclaim,--"I need a salvation omnipotent in its moral force; else I cannot stand." All this decay of moral vigor--this collapse in the moral system--this is what you need to overcome, and grace for this result is precisely the thing your case requires. You try to pray, but heart and language fail you! Ah, this sinking away from God--this perpetual gravitation earthward and sinward--how terrible! You must be delivered from this; and nothing else can deliver you short of this moral cleansing which is provided in the blessed gospel.

The thing you need is that the Holy Spirit should become a moral power in your soul, antagonistic to the moral forces there that urge you towards sinning. This is the antidote of God's own providing.

This death in sin is complete. Unless there be some supernatural power to counteract it, all your efforts will be vain--vain essentially for the reason that you are not disposed to make efforts to any practical purpose. When you receive this divine power to help, you will understand what this means--"I am the resurrection and the life." To have this resurrection-power and life of Christ in you working in you to do all his will--this is the cleansing which the gospel promises, and which you so greatly need. When you experience it, you will find it a most effectual influence. Then you will know how blessed it is to have a supernatural and ever-present power at hand on which you may perpetually lean. Unless this power takes possession of the soul, nothing effectual will be done. How often does it happen that "the light shineth in darkness, and the darkness comprehendeth it not." Do you understand this?

-Charles Finney, December 23, 1857, On Confessing and Being Cleansed From Sin
