JESUS MUST INCREASE. I MUST DECREASE. From Matthew Poole's Commentary: He must increase, in honor, and dignity, and reputation in the world; he is the rising sun, (to give you notice of which I was but as the morning star), he must shine every day more and more. But I must decrease. Order your copy of the T-Shirt with the beautiful image of this Bible verse on it today! $27.30 per shirt.
