God commands us to "know the heart of a stranger" (Exodus 23:9) and to feel solidarity with the stranger, for you, too, know what it is to be a stranger. To know the stranger is to know the enemy. To know the enemy is to know your own heart. To know your own heart is to know that God is both self and stranger, friend and foe. This knowing fills you with a deep and abiding courage and joy, and it is this joy that embraces the stranger and invites her or him to come to God through you.
