When the Christian Scriptures say that "God is no respecter of persons," what they mean is that God is never favoritistic or racially or religiously prejudiced. God is Love, and Love does not practice bigotry.
It is important for Christians to know this about their God, for the Jehovah of the Hebrew Scriptures ("Old Testament") was an extremist who did regularly practice religious and racial bigotry. He saw Israel, or the Hebrews, as "his chosen people," and, in essence, loved only Hebrews.
The God of Jesus, being Love, has no "chosen people." This is a human, limited idea that leads people to only bigotry. The Way is one of equality among all persons, and in this sameness of status, each and every being has a personal, and equal, relationship with the interior divine Mind of Love.
Israel, as a nation, and Judaism, as a faith, both have a right to exist, and to prosper. God (Love) certainly holds nothing against them. But neither do they enjoy any special blessedness, or any special position, before the Lord of Love, who loves all equally. To imitate this fine Love is our highest goal and calling. So, while accepting and loving all Jews, the Christian must also love all Hindus, Buddhists, agnostics, atheists, and others. For she is called upon to love both her friends and her enemies.
