“What about the millions of people who lived during and after the time of Christ, who never knew he existed due to geographical location? Seems rather arbitrary and unfair to condemn people for that.”
I strongly believe that grace through the death of Jesus Christ is the only way to heaven. However, can this is Grace be provided to someone who has never heard of Jesus is a different question.
Most Christians would say that a baby will not go to Hell— not because it is born without sin, but because they believe that God’s grace is made available to this baby. In the old testament, there is a pagan harlot named Rahab that the Bible says had righteousness attributed to her.
I’m not saying everyone goes to heaven, but I’d say no one really knows in the end exactly what happens according to God’s law, grace, and plan.
God wont let anyone slip away that is His.
