“Christ came to enlighten mankind. There are various religions outside His revelation where the followers are sincere—not just practicing demon worship—and where the soul is really trying to get through to God. I would say that, before the people have heard of Christ, these religions are fine as far as they go, but they will not get you to the goal. The goal is eternal life and the Kingdom of Heaven, and God came in the flesh to open this up to us. Therefore, Christianity is true; you can point to the various comparative elements of truth in other religions and often they are very profound, but they do not open up heaven. Only when Christ came to earth and told the thief, “You will be with Me in Paradise,” was heaven actually opened up to men.”
