"Heaven may not be a possible world when you take it in isolation by itself. It may be that the only way in which God could actualize a heaven of free creatures all worshiping Him and not falling into sin would be by having, so to speak, this run-up to it, this advance life during which there is a veil of decision-making in which some people choose for God and some people against God. Otherwise you don't know that heaven is an actualizable world. You have no way of knowing that possibility."

“Doubt is never simply an intellectual problem. There is always a spiritual dimension to doubt, as well. There is an enemy of your souls, Satan, who hates you intensely and is bent on your destruction and who will do everything in his power to see that your faith is destroyed. And therefore when we have these intellectual doubts and problems we should never look at them as something that is spiritually neutral or divorce them from the spiritual conflict that we are involved in. Rather we need to take these doubts to God in prayer, to admit them honestly, to talk to our Christian friends about them, to not stuff them or hide them, we need to deal with them openly and honestly and talk to people about them and seek God's help in dealing with them.”

“What good does it do to pray about anything if the outcome is not affected? I would say when God chooses which world to actualize, he takes into account the prayers that would be offered in that world. We shouldn't think prayer is about changing the mind of God. He's omniscient; he already knows the future, but prayer makes a difference in that it can affect what world God has chosen to create.”

“We've already said that it's the Holy Spirit who gives us the ultimate assurance of Christianity's truth. Therefore, the only role left for argument and evidence to play is a subsidiary role. I think Martin Luther correctly distinguished between what he called the magisterial and ministerial uses of reason. The magisterial use of reason occurs when reason stands over and above the gospel like a magistrate and judges it on the basis of argument and evidence. The ministerial use of reason occurs when reason submits to and serves the gospel... Should a conflict arise between the witness of the Holy Spirit to the fundamental truth of the Christian faith and beliefs based on argument and evidence, then it is the former which must take precedence over the latter, not vice versa.”

“In order to receive forgiveness, we need to place our trust in Christ as our Savior and the Lord of our lives. But if we reject Christ, then we reject God's mercy and fall back on His justice. And you know where you stand there. If we reject Jesus’ offer of forgiveness, then there is simply is no one else to pay the penalty for your sin – except yourself.”

“In general, Western culture is deeply post-Christian. It is the product of the Enlightenment, which introduced into European culture the leaven of secularism that has by now permeated Western society. While most of the original Enlightenment thinkers were themselves theists, the majority of Western intellectuals today no longer considers theological knowledge to be possible. The person who follows the pursuit of reason unflinchingly toward its end will be atheistic or, at best, agnostic.”

“The man who claims to have no need of philosophy is the one most apt to be fooled by it.”
