A new heart also will I give you, and a new spirit will I put within you; and I will take away the stony heart out of your flesh, and I will give you a heart of flesh. – Ezekiel 36:26

Justification without sanctification would be no salvation at all. It would call the leper clean and leave him to die of his disease; it would forgive the rebellion and allow the rebel to remain an enemy to his king. It would remove the consequences but overlook the cause, and this would leave an endless and hopeless task before us. It would stop the stream for a time but leave an open fountain of defilement which would sooner or later break forth with increased power. Remember that the Lord came to take away sin in three ways. He came to remove the penalty of sin, the power of sin, and last, the presence of sin…Our Lord Jesus came to destroy in us the works of the devil. That which was said at our Lord’s birth was declared in His death; for when the soldier pierced His side, there came out blood and water to set forth the double cure by which we are delivered from the guilt and the defilement of sin. If, however, you are troubled about the power of sin and about the tendencies of your nature, as you well may be, here is a promise for you. Have faith in it, for it stands in that covenant of grace which is ordered in all things and sure. God, who cannot lie, has said in Ezekiel 36:26, ‘A new heart also will I give you, and a new spirit will I put within you; and I will take away the stony heart out of your flesh, and I will give you a heart of flesh.’ You see, it is all ‘I will’ and ‘I will.’ ‘I will give’ and ‘I will take away.’ This is the royal style of the King of kings who is able to accomplish all His will. No word of His shall ever fall to the ground. ~ C.H. Spurgeon
