so perhaps we need to reaffirm our belief in what God has promised:
Eze 11:19 And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them a heart of flesh:
Eze 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.
God did not say he would leave our stony heart in us, he did not say he would simply put His Spirit within, and leave us in our fallen state.
Eze 11:19 And I will give them one heart, and I will put a new spirit within you; and I will take the stony heart out of their flesh, and will give them a heart of flesh:
Eze 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.
God did not say he would leave our stony heart in us, he did not say he would simply put His Spirit within, and leave us in our fallen state.
