How long is Israel blinded?
According to Romans 11:25, Israel has been blinded until the Fullness of the Gentiles is brought in. In other words, God is going to deal with the church or Israel as his vehicle for spreading the word but not both at once. When the church is out of here, Israel is back in the game. This doesn’t mean Israel is not part of God’s plan while the church is still here, so we do need to support the causes of God’s chosen people, but don’t be surprised when they’re not real ecstatic about the message of the Messiah.
