I’m not suggesting anything other than the God of the Bible will not excuse people simply because they never heard of Jesus Christ, just as He didn’t excuse the ancients who did not have the law and the prophets that ancient Israel was blessed to have.
God saves people today precisely the same way He saved people in the Old Testament. Abraham believed God and it was counted unto him for righteousness (Genesis 15:6, Romans 4:3, Galatians 3:6). It wasn’t his faith that saved him, it was the object of his faith. Abraham looked forward to a coming Savior, we look back on that same Savior.
Okay, well tell it to some Indians who lived in what is now called the America’s four thousand years ago. I’m sure they’d be real happy to know that they’re doomed.
