Heaven or Hell

Heaven or Hell. The Bible tells us that:
The Lord ...... is longsuffering toward us, not willing that any should perish but that all should come to repentance. (II Pet 3:9 NKJV)
At the same time, though, it says that:
.. wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. Because narrow is the gate and difficult is the way which leads to life and there are few who find it. (Matt 7:13-14 NKJV)
If I read the Bible correctly, it appears that most of the world's population is going to the bad place and only a few to Heaven. Why is that? This book explores possible reasons and what both Heaven and Hell might be like
