There are many sources of evidence that support the Christian faith.
New Christians would do well to at least get a fundamental understanding on the importance of these sources of evidence and how they interact with Christianity.

Old Testament Prophecy Evidence
Arguably the most compelling of evidences demonstrating that the Bible is the word of God is its unswerving ability to accurately predict future events, often in minute details. Specific prophesies are conspicuously absent from the 26 other religious books that claim to be scripture, including the Muslim’s Koran, the Book of Mormon, the Hindu Vedas, and Buddhist writings1. This in itself should be a major eye-opener to the honest skeptic. God through the prophet Isaiah once challenged the pagan idolaters of that time to “tell us what the future holds, so we may know that you are gods (Isaiah 41:23).”
It would be extremely difficult for the honest skeptic to dispute the overwhelming archeological support for the historical accuracy of both the Old and New Testaments. Numerous items discussed in the Bible such as nations, important people, customary practices, etc. have been verified by archeological evidence. Bible critics have often been embarrassed by discoveries that corroborated Bible accounts they had previously deemed to be myth, such as the existence of the Hittites, King David, and Pontius Pilate, just to name a few. The noted Jewish archeologist Nelson Glueck summed it up very well:
It may be stated categorically that no archeological discovery has ever controverted a single biblical reference. Scores of archeological findings have been made which confirm in clear outline or in exact detail historical statements in the Bible1.
In numerous instances the Bible contains medical information that far predates man’s actual discoveries of related principles in the field of medicine. The medical instructions given by Moses to the Israelites some 3500 years ago were not only far superior to the practices of contemporary cultures, they also exceeded medical standards practiced as recently as 100 years ago. Where did Moses get this advanced information?
Though the Bible is not a science book, when it touches on scientific matters it is either completely accurate or non-contradictory, and often demonstrates remarkable fore-knowledge. There are many scientific facts mentioned in the Bible that were not understood by man until centuries after the Bible was written.
A common misunderstanding of the Bible by both Christians and non-Christians alike is the mistaken notion that the Bible is a translation upon a translation upon a translation, leading some to believe that the end result is so garbled it hardly represents the original. This couldn’t be farther from the truth. Translations such as the King James version are derived from extant copies of old manuscripts such as the Greek Textus Receptus (Received Text) and the Hebrew Masoretic text, and are not translations of a text that had itself been translated from another interpretation. Often, the differences between Bibles with different translations lie only in how the scholars interpreted a word or sentence from the original language of the text source (Hebrew, Aramaic, or Greek).
Other Religions Evidence
To non-Christians one of the most offensive claims of Christianity is that it provides the only path to heaven. If you are a non-Christian it is certainly understandable why this would offend or upset you, but I would hope you can at least appreciate and respect why it is important for Christians not to skirt such an important tenet of Christianity.
