PREACHING AND MINISTRY OF JOHN. ( = Mar 1:1-8; Luke 3:1-18). (Mat 3:1-12) In those days--of Christ's secluded life at Nazareth, where the last chapter left Him. came John the Baptist, preaching--about six months before his Master. in the wilderness of Judea--the desert valley of the Jordan, thinly peopled and bare in pasture, a little north of Jerusalem.
