The Israel of God that was Promised Salvation is Spiritual, the Portion of humanity which is comprised of men and women of all nations and ethnicities. They are the only People which Christ was raised a Saviour to:
Acts 13:23
Of this man's seed hath God according to his promise raised unto Israel a Saviour, Jesus:
John 17:1-3
1 These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: 2 As thou hast given him power over all flesh, that he should give eternal life to as many as thou hast given him. 3 And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.
Rev. 5:9
And they sung a new song, saying, Thou art worthy to take the book, and to open the seals thereof: for thou wast slain, and hast redeemed us to God by thy blood out of every kindred, and tongue, and people, and nation; 10 And hast made us unto our God kings and priests: and we shall reign on the earth.
The Salvation of Israel from God's perspective is the Whole World Rom. 11:26; His Saints by His Adopting Grace Eph 1:4-5; 2 Tim. 1:9.
Ps. 148:14
He also exalteth the horn of his people, the praise of all his saints; even of the children of Israel, a people near unto him. Praise ye the LORD.
