In the Sermon on the Mount, Jesus reveals to us what we truly need to be in relationship with him--to walk with him, to be who he created us to be. The blessing of a pure heart is that we SEE God. We understand grace. And we SEE because we get what God is calling us toward and willingly let go of what blinds us. "Seeing God" is evidence of the change grace makes in our lives--what a pure heart leads to.
