When God first created man, He created him to grow to perfection only by completing his portion of responsibility. Therefore, man could either accomplish his portion of responsibility in accordance with God's will, or, on the contrary, not accomplish it, going against God's will. Therefore, it was inevitable that God give two kinds of prophecies, one for each possibility, regarding the fulfillment of His will.

It was God's portion of responsibility to send the Messiah, but it was man's portion of responsibility to believe in him. Unfortunately, the Jewish people failed to fulfill their portion of responsibility by not accepting Jesus; they did not fulfill God's primary prophecies of the Messiah's coming in Isaiah 60 and Luke 1:31-33, but, on the contrary, carried out the alternative or secondary prophecy of the suffering Lord in Isaiah 53.
