Ezekiel 36:26 I will give you a new heart and put a new spirit within you; I will take the heart of stone out of your flesh and give you a heart of flesh.
God wants to change us from the inside by removing the heart of pride that we have and replacing it with a servant heart willing to work with Him.
If we have a heart that did not care we would be just like the animals out there, just doing stuff because that is what we do.
God gave us hearts to love one another and we need to allow that love to work from within, not block it out.
