Ezekiel 36:26

A new heart also will I give you, so that mind and will would be regenerated, and a new spirit will I put within you, so that their entire motives and principles of action would be changed in conformity with God's will, Psalms 51:10; and I will take away the stony heart out of your flesh, the natural enmity against God, and I will give you an heart of flesh, one that will readily receive the impressions of God's Holy Spirit and be guided by His power in all good works.
