God promises us a new obedient heart
Ezekiel 36:25-27 I will sprinkle pure water on you and make you pure. I will wash away all your filth, the filth from those nasty idols, and I will make you pure. I will also put a new spirit in you to change your way of thinking. I will take out the heart of stone from your body and give you a tender, human heart. I will put my Spirit inside you and change you so that you will obey my laws. You will carefully obey my commands.
God promises to give us a new obedient heart and fill us with the Holy Spirit so we can make the right choices in our lives and follow His program.
