One cannot be classified as an Israelite in the real sense of the word unless they have overcome the world, sin, Satan and self through their faith in God; overcomers are spiritual Israelites. Notice that the patriarch Jacob had his name changed to “Israel” only after he wrestled with God and prevailed (Genesis 32:28). The word “Israel” means “God is Sovereign”. So self which was Jacob’s biggest and final enemy was subdued and God’s sovereignty, glory and power could now be expressed evidently through his life. Consequently, he became an overcomer. Overcomers are prevailers; they are those who have learnt to prevail with God. They are those who will make up the CHURCH (Ekklesia) of the Lord Jesus Christ (Revelation 7, Revelation 14:1-5).
If so, where does that put the physical Jews or Israelites?
