This handbook is designed to help all believers to have a better grasp of the Bible. But it is also written with the Jewish people in mind. Without the Jewish history, there would be no Christianity.
John 1:11 declares that Jesus came unto His own (the Jewish people), and His own received Him not (they rejected Jesus as their Messiah). As a result, salvation has come to the Gentile nations (Romans 11:11).
The apostle Paul uses an olive tree as a metaphor in Romans 11:24 to explain an integral truth. Paul, in that text, says that we as Gentiles who were considered wild by nature (non-Jews) were grafted into the natural olive tree (Jews), along with the natural branches, through Jesus Christ, who is God's chosen One to reconcile both the Jews and the Gentiles into one covenant. This metaphor speaks not only of two differing races of people uniting together in one covenant, but it speaks to the fact that Judaism and Christianity are dependent upon each other. One cannot do without the other. They are divinely intertwined. Hence, we have the term "Judeo-Christian."
God intended that the Jewish nation was to be a prototype of the church body of Jesus Christ. This handbook reveals that process of God's divine plan. It will be obvious as you wade through the pages of this handbook--the unfolding of the plan of God from ages past. It will reveal how God has worked through obstacle after obstacle to produce a solution for all people regardless of religion, race, color, culture, or gender.
