To truly welcome a prophet is itself a way of growing whole, because only a person who already carries the same deep pattern within can recognize it moving through someone else.
Opening your door to one who carries the image of God is no plain courtesy. Something in the host is claimed, a sleeping shape stirs toward awareness. Yet the nearer danger is self-importance dressed up as welcome: the follower who basks in the prophet's glow, swelling in reputation while the Master carries all the weight, never meets that deep pattern honestly.
The reward named for the good, which is peace, belongs only to the one who goes through the same inner demand the prophet answered.
