Q. Do you believe that the time of tribulation is predominantly to bring Israel to the knowledge of Jesus? This is what I have always heard.
A. According to Jeremiah 30:11 the purpose of the Great Tribulation is two-fold. One is to completely destroy the nations among which the Jews have been scattered, and the other is to discipline Israel. This discipline will cause them to recognize Jesus as their Messiah, and will happen in several stages.
The first is when as a nation they return to their Old Covenant relationship with God following the Battle of Ezekiel 38 (Ezekiel 39:22) prompting the building of a Temple in Israel. This when Daniel’s 70th Week will begin. The second is when they petition God’s return to save them (Hosea 6:1-2), and the third is near the end of the Great Tribulation when they realize that Jesus has been their Messiah all along (Zechariah 12:10).
