“God does more than “hold” a heart. He seizes it. The verb translated as “seize” is not a gentle one. It suggests that God will grab onto His people in order to pull them away from their idols.
God suddenly pierces your chest and seizes your beating heart. If that were to actually happen, you would freeze in place. He would have your heart, but you would be all ears.
Maybe you’ve had the experience of having to grip a toddler tightly as they race into traffic. God seizes your heart, or tries to, when He sees you headed for the broad way that leads to destruction.
It can have a physical component, both for unbelievers & believers. I have a very present memory of the Lord seizing my heart when I got saved. I knew that was dead inside, and yet I was alive and going to be struck dead. It was the conviction of the Holy Spirit.”
