Rom 3:22 … the righteousness of God [comes] through faith in Jesus Christ for all who believe.
Rom 9:13 As it is written, “Jacob I loved, but Esau I hated.”
God does have his favourites in the sense that he rewards some people and not others. As Romans 3:22 indicates, those who believe and are faithful are his favourites. In the case of Esau and Jacob, God in his foreknowledge was aware that Jacob would be faithful to him, but Esau would not, so Jacob received the greater blessing.
In another sense, God treats everyone exactly the same.
“For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. (John 3:16)
The Lord is not slow to fulfill his promise as some count slowness, but is patient toward you, not wishing that any should perish, but that all should reach repentance. (2 Peter 3:9)
