If you yield yourself up to His divine working, the Lord will alter your nature; He will subdue the old nature, and breathe new life into you. Put your trust in the Lord Jesus Christ, and He will take the stony heart out of your flesh, and He will give you a heart of flesh. Where everything was hard, everything shall be tender; where everything was vicious, everything shall be virtuous: where everything tended downward, everything shall rise upward with impetuous force. The lion of anger shall give place to the lamb of meekness; the raven of uncleanness shall fly before the dove of purity; the vile serpent of deceit shall be trodden under the heel of truth.
Charles Spurgeon
