Israel is still waiting for the Messiah to come because they reject Jesus as their Messiah, the church is waiting for the second coming (appearing) of Jesus which church considered their blessed hope. Who deserve the wait?
Jesus is coming back for ALL those who believe in Him and love Him. The seven year tribulation is when many Jews are going to finally accept Christ as the Messiah and convert. God has given us two thousands years to come around. To answer your last question, no one deserves the wait. Jesus' sacrifice was a gift of grace and mercy bestowed upon those who can't earn it for themselves.
