“Who can count the dust of Jacob or number the seed of Israel.” Numbers 23:10

Reading this, I envy those Jews who love Israel (as do I) and worship the God of our fathers, and reverence the land of their ancestors.
But as a Christian I have always thought myself part Jewish, since three fourths of our Bible consists of the Old Testament. And Jesus was a Jew, of the house of David.
