John 3:30

“He must increase, etc.] Not in stature of body, or in wisdom and understanding of mind, as man, he being come to maturity in these things already; but in fame, credit, and reputation among men; as he afterwards did in the land of Judea, by reason of his miracles and doctrines; and after that among the Gentiles, through the publication of his Gospel; and will more and more in the latter day, when he, and he alone, shall be exalted: and he must increase in the ministry of his word, which was published by him, and his disciples, throughout all the cities of Israel; and which, after his resurrection and ascension, grew and increased mightily, notwithstanding the opposition made unto it both by…”
