Believe not that God is in your heart child, but rather that you are in the heart of God

I have always thought it's good that we believe that God's in our hearts and that we teach it to children this way. Yet, then I heard this line in a Mraz song. I think he's right. Just the picture that it creates of Him being in our hearts versus us being in His heart. I think us being in His heart puts Him as the larger being and shows it more correctly. After all, the only reason that we are even able to have Him in our hearts is because we are in His.

What do you do.... when God moves through you?
