1 Sam. 16:7. But the LORD said to Samuel, "Do not look at his appearance or at the height of his stature, because I have rejected him; for God sees not as man sees, for man looks at the outward appearance, but the LORD looks at the heart." NASB

God does not look and judge people by their outward appearance or nationality. The Jews were once God's favorite for the sake of the promise to Abraham; but not any more. All men are equal in God's sight whether Jew or Gentile and God is not partial towards any.

And opening his mouth, Peter said: "I most certainly understand now that God is not one to show partiality, but in every nation the man who fears Him and does what is right, is welcome to Him." Acts 10:34-35 NASB

"For there is no distinction between Jew and Greek; for the same Lord is Lord of all, abounding in riches for all who call upon Him;" Romans 10:12 NAS

These are only a few passages that show that God's dealings with mankind are equitable and just. God's judgments towards mankind are not formed by prejudice.
