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 When Jesus speaks of a new heart, He means the mind, the life, the whole being. To have a change of heart is to withdraw the affections from the world and fasten them upon Christ. To have a new heart is to have a new mind, new purposes, and new motives. What is the sign of a new heart? - a changed life. There is a daily, hourly dying to selfishness and pride.
