Standing With and United for Israel!
It's my firm conviction that all Christians should stand with and be united for Israel. In fact, the very title of "Christian" ("Christ-like follower") is contradicted when we fail to do this, since standing with Israel is the foundation of our faith.
Also permit me to add one more confession and conviction: In addition, I have abandoned replacement theology.
However, let me clarify my position concerning standing with, being united for, and abandoning replacement theology relating to Israel by asking and answering this question:
Who is Israel?
According to the progressive revelation of Scripture as found in the New Testament, who is Israel?
“And He said to me, ‘You are My servant, O Israel, in whom I will be glorified.’ Then I said, ‘I have labored in vain, I have spent my strength for nothing and in vain; Yet surely my just reward is with the Lord, and my work with my God.’ And now the Lord says, Who formed Me from the womb to be His Servant, to bring Jacob back to Him, so that Israel is gathered to Him (For I shall be glorious in the eyes of the Lord, and My God shall be My strength), indeed He says, ‘It is too small a thing that You should be My Servant to raise up the tribes of Jacob, and to restore the preserved ones of Israel; I will also give You as a light to the Gentiles, that You should be My salvation to the ends of the earth’” (Isaiah 49:3-6).
Who is the one referred to in the above passage as "My servant, O Israel"?
Albert Barnes (1834), Adam Clarke (1831), John Gill (1746), The Geneva Study Bible (1599), Jamieson/Faussett/Brown (1882), Matthew Henry (1708), The Pulpit Commentary (1880’s), and John Wesley (1754) all stand in agreement that Isaiah was speaking here of Jesus, and that Isaiah referred to Jesus as “Israel.”
Adam Maarschalk walks through a brief progression of Biblical revelation regarding the promise recorded in Genesis 12:3:
 It was first made by God to Abraham alone: “It will be through you [Abraham], that all the families of the earth will be blessed.”
 It was repeated again in Genesis 22:18, and this time expanded to include his offspring: “And through your offspring all nations on earth will be blessed, because you have obeyed Me.”
 In Acts 3:25-26, the apostle Peter, speaking to a Jewish crowd in Jerusalem, is clear in identifying Abraham’s offspring and the means of blessing for the nations: "And you are heirs of the prophets and of the covenant God made with your fathers. He said to Abraham, ‘Through your offspring all peoples on earth will be blessed.’ When God raised up His servant, He sent Him first to you to bless you by turning each of you from your wicked ways.” It’s Jesus who is Abraham’s offspring, and He blesses the nations, beginning with the proclamation of the gospel to Jews in the first century.
 The apostle Paul, in Galatians 3:7-8, declared that Jesus’ followers are Abraham’s offspring too: “Understand, then, that those who believe are children of Abraham. The Scripture foresaw that God would justify the Gentiles by faith, and announced the gospel in advance to Abraham: ‘All nations will be blessed through you.’”
The essential elements of Israel's life as a covenant people (prophet, priest, king, sacrificial system, ark of the covenant, etc.) were all fulfilled in the person and work of the Lord Jesus Christ (Luke 24:27, 44
