Excerpts from this blog post of the same name written by Preston Gillham:
The Scriptures are clear, we Believers are given a new heart when we are transferred from the kingdom of darkness into the kingdom of light, from irretrievable uselessness to God to being His sought after treasure. No longer do we have hearts that are rebellious and desperately wicked as Jeremiah preached to his generation. Rather, as Ezekiel prophesied would be the case when Christ came, the laws of God are now written on our hearts; they are no longer hardened to God but are soft and pliable (ref. Ezek. 36:26-27).
It is a crying shame that teachers teach and Believers believe that the heart of the child of God is a wicked beast torn between two loves: obedience and sin, God and the devil, darkness and light. This is a mishandling of Scripture, and I think sometimes it is deliberate in order to motivate folks toward outward godliness in lieu of true spiritual formation, which begins inside and works its way out. You would think we were forming Pharisees instead of people who follow Christ with all their heart...
It is for this reason that the Scriptures are emphatic, and that Ezekiel’s prophecy is important, regarding the condition of our hearts. Our hearts are new, not old; soft, not hard toward God; clean, not in the condition of the folk’s hearts whom Jeremiah preached to in real time versus prophetically.
This is important because we are designed to live from our hearts. The heart is the core of us, the deepest and most thoroughgoing aspect of us. It governs all that God desires to have come out of us. From the heart we passionately convey God to others during our daily trek through life.
When Jesus appealed to His disciples and presented the kingdom to them, He appealed to them at their basic ability to respond to God—their hearts. He does the same with us, and the devil—our adversary—recognizes this and wages an insidious battle to undermine our determination to live from our hearts. Thus the reason behind the heart-level wounds we have all suffered with this, it is all the more apparent why Proverbs 4:23 says, “Watch over your heart with all diligence, for from it flow the springs of life.”
We attempt to live from our heads, from our theology, from our tradition, from our emotion, from our family history, from what we are taught, from our accomplishments, ad infinitum. But we must adopt God’s viewpoint of life and of our lives. He designed us to live passionately, intensely, confidently…and to do so from a heart that is clean and pure based upon the finished work of Christ (ref. Heb. 10:19-25). Be encouraged in your heart!
