Out of all the billions of people inhabiting God’s created earth over time God chose the descendants of Abraham, Isaac and Jacob to be the race through which He would bless all nations (save all people). Out of all the millions of geographical locations on earth God chose Zion (Jerusalem) to be the spot from which He would redeem all nations.
Israel, the land and the nation, flows through Christ and comes out as the Church. Zion, the city and the Temple, flows through Christ and comes out as the Church. Out of the Church flows the Word that saves and into the Church flows the people who are saved from all the nations. The Church then is the Mother of all believers in Christ and God registers them as “born in Zion.”
The Gentiles, the nations, the Muslims, the secularists, the heathen, and every other unbelieving group of people are not the enemies. They are potential family members, who are presently under the sway of the enemy; they are to be rescued and born into the kingdom of God (Zion) through the Gospel. The true enemies (Sin, Death, Devil) cannot be redeemed, changed, or improved; they must be crushed.
