God's choices of who will be saved from the mass of humanity comprised of Jews and Gentiles are all sinners by birth and by choice. God is not obligated to save sinful beings; however, He is obligated to dispense justice. He has chosen to demonstrate His love, grace, and mercy toward the very people He hates without obligation. God makes His choices consistent with His own character. No person can earn their salvation no matter how hard or what kind of effort they make. Salvation would not be by grace if works of any kind were to be added to it.
