Your "spiritual Israel" is a fiction COMPLETELY missing from scripture. You cannot quote even one scripture that says any such thing. All you can do is quote scriptures which YOU INTERPRET to MEAN that.
Jesus is Israel.
“Now to Abraham and his
seed were the promises made. He saith not, And to
seeds, as of many; but as of one, And to thy
seed, which is Christ.” Galatians 3:16 (KJV 1900)
“For
all the promises of God in him are yea, and in him Amen, unto the glory of God by us.” 2 Corinthians 1:20 (KJV 1900)
Moses and Paul called Abraham’s seed both Hebrews and Israel.
“Now there was no smith found throughout all the land of
Israel: for the Philistines said, Lest the
Hebrews make them swords or spears:” (1 Samuel 13:19)
“Circumcised the eighth day, of the stock of
Israel, of the tribe of Benjamin, an Hebrew of the
Hebrews; as touching the law, a Pharisee;” (Philippians 3:5)
“And they shall hearken to thy voice: and thou shalt come, thou and the elders of
Israel, unto the king of Egypt, and ye shall say unto him, The Lord God of the
Hebrews hath met with us: and now let us go, we beseech thee, three days’ journey into the wilderness, that we may sacrifice to the Lord our God.” (Exodus 3:18)
“Then said the princes of the Philistines, What do these
Hebrews here? And Achish said unto the princes of the Philistines, Is not this David, the servant of Saul the king of
Israel, which hath been with me these days, or these years, and I have found no fault in him since he fell unto me unto this day?” (1 Samuel 29:3)
“Are they
Hebrews? So am I. Are they
Israelites? So am I. Are they the
seed of Abraham? So am I.” (2 Corinthians 11:22)
Therefore Jesus IS
Israel,
Abraham’s Seed (Singular Galatians 3:16) along with believers. “And if ye be Christ’s, then are ye
Abraham’s seed, and heirs according to the promise.” Galatians 3:29 (KJV 1900)
