PROPHETS, WHY THEY BECAME A MEDIUM BETWEEN MAN AND GOD.

Since ALL INSTITUTIONALIZED RELIGIOUS OBSERVANCES are prone to become AUTOMATIC PRACTICES, WITHOUT FULL UNDERSTANDING OR SPIRITUAL AWARE-
NESS on the part of the practitioner, so among the HEBREWS spokesmen AROSE WHO DENOUNCED the INSINCERE practice of HEBREW RITUAL.
These SPOKESMEN were the PROPHETS. The PROPHET was a man, one through whom DIVINE
WILL and PURPOSE WAS KNOWN, and believed  to be specifically summoned by GOD to PREACH GOD's MESSAGE. Read this biblical passage from Luke:
LUKE 1 : 68 BLESSED BE THE LORD GOD OF ISRAEL; for HE HAVE VISITED and
                      REDEEMED HIS PEOPLE.
                 69 And HAVE RAISED UP A HORN OF SALVATION FOR US IN THE HOUSE
                      OF HIS SERVANT DAVID;
                 70 As HE SPOKE BY THE MOUTH OF HIS HOLY PROPHETS, WHICH HAVE
                      BEEN SINCE THE WORLD BEGAN:
                 71 That WE SHOULD BE SAVED FROM OUR ENEMIES, and FROM THE HAND
                       OF ALL that hate us;
                 72 To PERFORM the MERCY PROMISED TO OUR FATHERS, and to REMEMBER
                       HIS HOLY COVENANT;
                 73 the OATH which HE SWORE TO our father ABRAHAM,
                 74 that HE WOULD RESCUE US FROM the ENEMY HANDS and MIGHT SERVE
                      HIM WITHOUT FEAR.
                 75 IN HOLINESS and RIGHTEOUSNESS BEFORE HIM, ALL THE DAYS OF OUR
                      LIFE.
It is evident that the prophetic experience was both IRRESISTIBLE, overcoming the protest of a Moses (Ex.4:10), an Isaiah (Is.6:5), and  a Jeremiah (Jer.1:6); and TRANSFORMING, turning as it
did to Saul "into another man" (1Sam.10:6)
