The Soul & the Spirit
I’m confused about the difference between the soul and the spirit. Do we have both of these things? What is the difference between them?

Once saved, always saved?
Can a Christian lose their salvation? If not, how do you explain Heb. 6:4-9 and 10:26-29, which talk about eternal judgment on those who continue to sin after having shared in the Holy Spirit and been sanctified by the blood of Christ? Doesn't this idea of "once saved, always saved" promote spiritual apathy, anyway?

Predestination
Are we predestined to salvation? If we are, doesn’t that mean that we have no free will?

Pluralism: Many Ways to Heaven?
I once was telling someone that I believe that salvation is only through Jesus Christ, and they said to me, “So everyone who disagrees with you is going to hell?” There are a lot of sincere religious people out there, and it’s unpopular to tell people that only Jesus can save them. Some people have pointed out that Christianity cannot be the one true religion because so many Christians are hypocrites, and Christians all fight over what the Bible means. How do I answer these challenges?

New Age Spiritism
I have a friend who says that a guardian angel comes and speaks to him, and gives him knowledge of the future. I have also heard of people communicating with the spirits of people who are dead. What does the Bible teach about this?

Satan and Demon Possession
What does the Bible teach about demons, Satan, and their work in the world? Can Christians be demon possessed?

Salvation of the Ignorant
Can people who have never heard the gospel be saved? What about a guy who lives on a deserted island his whole life? Does God judge him the same way as people who had an opportunity to accept Christ?

The Problem of Evil
Why does God permit evil and suffering to exist? If He was real, wouldn’t He do something about it? Why do bad things happen to good people?
