If your going to use Israel for doctrine, you must use all of her history, not just selective, out-of-context cherry picking, such as you’re engaging in, IMO.
God called Israel for no special reason. God kept Israel even when they rebelled and apostatized. God kept Israel even though they crucified His Son. God kept Israel even though they were cut away from the vine and Gentiles were grafted in. God promises to save Israel in the end (Is 66:7-9; Zech 12:10-13:1) so that even their disobedience will exalt His mercy (Rom 11:32).
Just as God has remained faithful to undeserving Israel, so will He be faithful to
undeserving believing sinners. God will never annul His promise or cast out those who have come to Him through Christ (Jn 6:37; 17:2).
God’s promise comes by faith, so that it may be by grace and be guaranteed to those who have faith (Rom 4:16). Justification is assured when one believes. Those who think justification can be earned or maintained by human faithfulness nullify God’s grace and His promise of eternal security. Anyone who counts on attaining and preserving justification can have no assurance.
Right you are.
Actually, if you continue reading the passage, you’ll find those who Christ never knew are those who plead their works for justification (v22).
Moral assurance? Paul doesn’t preach moral assurance.
That’s an old, hackneyed appeal to emotion.
C’mon, Paul is speaking rewards (v18).
Moses is a prime example of one who was disqualified from finishing the race,
but still reaped the benefits of eternal life. Paul’s not speaking of justification in that passage—he knew his citizenship is heaven (Php 3:20).
Biblical hope is a confident hope based upon the promises of God; it’s not a hope-so-hope, based upon a moral assurance.
BTW, what is a moral assurance, elvisman? (Bet it has to do with your works.)
