If we only had the New Testament, we would come to the Gospels and not know why the Jews were looking for a Messiah (a Savior King).
Kung mayroon lamang tayong Bagong Tipan, tutunghayan natin ang Ebanghelyo at hindi mauunawaan kung bakit ang mga Hudyo ay naghihintay sa isang Mesiyas (isang Hari at Tagapagligtas).
