"What happens to those who never get a chance to hear the Gospel and die before they do get a chance?"
No one will go to Hell because they haven't heard of Jesus. They will be condemned for murder, rape, adultery, fornication, lying, stealing, etc. Put your concern for others to hear the gospel aside for the moment. If you died right now you will justly end up in Hell. Get right with God and become a missionary, if you really care about the lost.
“If I were God, I'd hate to have you people speaking on my behalf.”
We do our best, but we are fully aware that “God has chosen the foolishness of preaching to save those who believe” (see 1 Corinthians 1:21). He chose the weak vessels of human beings to take the message of everlasting life to weak and dying human beings.
“If your God was so great, I would see no reason why He would need to force people to submit to Him in worship.”
We are free to be unthankful for our eyesight, hearing, food, sunlight, and all the pleasures He has lavished onto us. But if we die in our sins, we will get justice. That’s why we need a Savior. When He opens our eyes through the new birth, worship comes as easily as songs do to an early morning songbird.
“Are you saying that Christians are better than non-Christians?”
The Christian is no better than a non-Christian, but he is infinitely better off. It is like two men on a plane, one of whom is wearing a parachute while the other is not. Neither is better than the other, but the man with the parachute is certainly better off than the man who is not wearing a parachute. The difference will be seen when they jump from the plane at 20,000 feet. Jesus warned that if we “jump” into death without Him, we would perish. The Law of an infinitely holy and just Creator is even harsher than gravity. Scripture states that sinners are God’s enemy (Romans 5:10) and that “It is a fearful thing to fall into the hands of the living God (Hebrews 10:31).
The purpose of the moral Law (the Ten Commandments) is to stop the sinner’s mouth of justification. The Law tells him what sin is (see 1 John 3:4) and stops him proclaiming his own goodness. Its intent is to drive him to the cross. John Wesley said, “The first use of [the Law], without question, is to convince the world of sin. By this is the sinner discovered to himself. All his fig-leaves are torn away, and he sees that he is ‘wretched and poor and miserable, blind and naked.’ The Law flashes conviction on every side. He feels himself a mere sinner. He has nothing to pay. His ‘mouth is stopped’ and he stands ‘guilty before God.’”
D. L. Moody said, “Ask Paul why [the Law] was given. Here is his answer, ‘That every mouth may be stopped, and all the world may become guilty before God’ (Romans 3:19). The Law stops every man’s mouth. I can always tell a man who is near the kingdom of God; his mouth is stopped. This, then, is why God gives us the Law—to show us ourselves in our true colors.”
