Good answer, Sue!Salvation was 1st to God's chosen people -- the Jews and Then extended to the Gentiles (the rest of the world) Because the Jews - as a people group - would Not accept Jesus Christ as their promised Messiah.
Part of that is found in Acts 11:19 - 25 or so. Matthew 15;24 -- lost sheep of Israel Romans 1:16.
So 'we' are presently living in the time of the Gentiles -- at some future point in time -- the Church will be taken up and out of this present world to be with Jesus Christ. During the next 7 yrs. , God Will be dealing, once again with the Jewish population. that are still here.
In the Big picture -- God knew that salvation would be extended to Everyone. That's why He provided salvation for All.
