Wow, this forum has really touched on some interesting topics.
Couple of points:
- Correct that Jesus Christ is God, but He is God in the sense of the Trinity, i.e. three in one. He is also a separate personage of the Trinity, which is very clear in Scripture. Scripture is also clear that you cannot worship God without also worshipping Jesus Christ His Son. If one believes in God, but rejects Jesus Christ, then the Bible says that that person per se has also rejected God (cf. John 5:22-23, I John 2:23). God says that if you reject His Son you have rejected Him, no exceptions.
- The Old Testament has hundreds of prophecies looking forward to Jesus Christ, the Messiah. Though not called Christians, those Old Testament saints that believed in God and died believing in and looking forward to the Coming Messiah are saved. In chapter 16 of the book of Luke we are given a description of what happened to the Old Testatment saints between the time they died and the Coming of Jesus Christ in the story of Lazarus and the rich man. Some look this as a parable, but proper names are never used in parables, so this was an actual account being given by Jesus. Old Testament saints, when they died, were sent to an interim location to await the Coming of Jesus Christ. Once He came, died for our sins, and paved the way to salvation, the Old Testament saints could then enter into heaven. Those that died after the Cross had/have a direct flight to heaven with no stopovers.
- Yes, all other religions are wrong and will not lead to heaven, but will lead to an eternity in a very undesirable place. Jesus told His disciples in His Sermon on the Mount that the road to heaven is narrow and only few will find it, but the road to hell is wide and many will unfortunately take that path (cf. Matthew 7:13-14). There is one way to heaven, that being Jesus Christ. Any belief that tells us otherwise, including all of the other religions, which are the wide roads, is the most harmful of deceptions.
- How can I be so bold as to say that Christianity is the only true religion? The Bible, God's Word and the foundation of Christian beliefs, is the only religious book that can be authenticated beyond a doubt that it was written by the God of the universe. How is that? By the hundreds of prophecies written in the book that are 100% accurate about future events. Only the true God could have written (i.e. written through men) such a book--a God that is outside of time. Prophecy is God's signature on His Book. Think about it. What better way for God, knowing that there would be many false religions and religious books in the world, to let us know that the Bible is the one true Book of God.

These questions being raised are very exciting to discuss.
