If you’re looking to be religious, and just trying to find someone to give you a good reason to believe that perhaps there is a God, maybe Christianity isn’t right for you.

Try researching Buddhism. I, myself live this lifestyle. :]

Opinion

The Bible was never suppose to be taken literally. The problem with the Bible is that people simply have not studied its history to know enough about it. They blindly follow the book even though that was not its purpose.

As for helping mankind, that is a tricky question. We can look at Christians who have helped mankind. Christian organizations have raised millions of dollars in order to help the poor and other people in need. For some people, Christianity gave them a direction to go with their lives. Then again, many people have been killed in the name of it. Christianity itself has done nothing to help mankind except for influencing people to do what is right. So it really are the Christian people who have helped mankind. And they have done so greatly.

Christianity is not better than any religion. It’s core teachings, are the same as nearly any other of the major religions. The one big difference that it has is the idea that Jesus was the savior of all humankind. However, different people need different ways to worship God. Some feel Christianity is best, others feel Islam is the best, and so on. It is simply another way to worship a god that works for some people.

The only reason to convert to Christianity, in my opinion, is if you want to worship God like a Christian. Christian is a very broad term as well. I very loosely define myself as a Christian, and a large majority of Christians would even contest that label for myself. In the end though, if you want to worship God, then it doesn’t matter if you are Muslim, Jew, Hindu, Christian, or whatever. You could worship God in hundreds of ways, and call him what ever name feels sweet on your lips. In the end, its simply a personal choice that no one could convert you too. The whole idea that Christians can convert people to their religion is simply futile.

http://watchtower.org/e/publications/index.htm > #9

Its contents begin with the chapters:

Why Be Interested in Other Religions?
Religion—How Did It Begin?

The next chapters each cover one (or, 2 that are very similar) of the major world religion’s histories, basic beliefs, practices, & customs. This makes comparing them a much easier task! The book has been used as a collage textbook, even though it doesn’t seem much like one, because it is easy to hold in one hand, & also easy to understand! The religions covered in its remaining 14 chapters are:

– Mythology – Magic & Spiritism – Hinduism – Buddhism
– Taoism & Confucianism – Shinto – Judaism – Christianity
– Apostasy from Christianity – Islam – The Reformation
– Modern Disbelief – A Return to the True God
– The True God & Your Future

You don’t have to click on the Scripture-reference-links, or, read the Scripture quotes. The remaining facts in the above-listed articles are both logical & quite convincing, all by themselves. But, you won’t know what you’re missing!

Jesus lives forever. How do I know? If you go to the tomb of Buddha, what do you find? If you go to Joseph Smith’s grave, what do you find? I can go on and on naming every "Allah" or "Muhammad" in the book. You would find the body. But, what if you went to Jesus’ tomb… You would find that the God we know is the only one who has risen above to Heaven.

Another thing…

For those Greek God believing folks… Jesus walked on water. You could say he walked all OVER your Gods!

I think it’s good because it strengthens your own morality – working on the basis of love your neighbor and the ten commandments, the religion adds like an extra incentive to follow your conscience. It instpires people to help others, and it makes you less afraid of dying and the like.

Wheather it’s true or not, it seems as though nowadays it’s more a force for good that evil.

As for the bible, I think they did prove that there was a bright star over bethlehem at the time, and all those folk who claim to have had near death experiences and give up all their wealth (which you wouldn’t expect a lier to do.)
