There are so many times in scripture where we see God "turn them over to their own stubbornness" or "remove his hand from them" or "allowed them to walk in their own devices." This happens over and over again, and it is striking to realize this characteristic in God the Father. He will as often in Scripture say things like "Oh that my people would listen to me, that Israel would walk in my ways."
This is not the "Old Testament God", as if God goes away to summer camp between testaments to really work on Himself. This is Almighty unchanging God we see here. Jesus does give us an access to God and His grace we could never give to ourselves, but let us realize God's action toward our stubbornness has not changed.
There come times when we choose to disobey God enough times that He will just let us go down that road to experience the pain and the brokenness He would have protected us from if we had only listened and obeyed him in the first place.
This is sobering to our hearts that are prone to wander. We must intentionally keep our hearts focused, open, and obeying, or we may very well see God remove his hand from our stubborn hearts.
