A NEW HEART
Ezekiel prophesied of a phenomenal heart change in the new covenant.
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.
Thank the Lord, he gives us a completely new heart. The entire old heart is removed, and we are given a new one.
This lines up with the Apostle Paul's teaching in the New Testament: Therefore, if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new. (2 Corinthians 5.17)
Because of this new heart and new spirit, we are partakers of the divine nature, and we are enabled to walk in newness of life.
