This is a topic that can be very controversial and a lot of very solid, Jesus loving Christians disagree. Remember, we can disagree in a way that displays grace.
There is a popular belief out there that Christians have to support the nation of Israel in political matters. I have recently heard a Dispensationalist pastor say Christians must support Israel because they are “God’s chosen people.” Pastors like John Hagee will even tell you things like if a country chooses to not support Israel then God curses that country and will bring judgment upon them.
While there are extremely valid political reasons to support the nation of Israel, there is no theological reason to support the nation of Israel in political matters any more than you support any other country. If your political convictions drive you to support Israel for political reasons- great. There is certainly nothing wrong with supporting Israel for political convictions. The problem is that sometimes Christians think we are scripturally mandated to support Israel politically. Many people who think Christians are mandated to support Israel politically usually do it because of their understanding of Israel as the “people of God.”
This is what I want to examine. The Bible clearly teaches that there is only one people of God, but many people seem to think that there are two people of God: Israel and the church. Ephesians 2 clearly teaches that through the cross and resurrection Jesus has broken down the “wall of hostility” between Jews and Gentiles and made himself one new man- the church (vs. 13-22). Therefore, Christians do not have a theological obligation to support Israel with the reasoning of Israel being the “people of God.” We should not separate Israel and the church as two different peoples, when Ephesians 2 very pointedly shows us how the two are bound together as one through the death and resurrection of Jesus. Scripture tells us that God, through His Son, is making one new man made up of both Jew and Gentile.
Galatians 3:16 also gives us good insight into this matter. It teaches that the promises of Abraham were not given to Abraham and all of his descendants, but to Abraham and his descendant (singular), and that is Jesus. This means that the promises of Abraham were not ever given to the entire nation of Israel, but the true Israel-Jesus. The partakers in the promises only partake because of their union with Jesus. Therefore, we should not be waiting on fulfillment in the nation of Israel, but understand that Jesus has fulfilled and is fulfilling the promises of Abraham.
With the Bible teaching that there is one people of God- the church- who is all those united to the True Israel- Jesus: then Christians have no theological obligation to support the nation of Israel. We all have the right to our political opinion and if yours leads you to support Israel that is great (mine do), but the Bible doesn’t demand that Christians support the nation of Israel for theological reasons.
