For some, the first obstacle for considering Christianity is believing the Bible is rock solid and believable and not just the words of a bunch of delusional people that sat under trees and made stuff up to see if they could fool the world. Of course, that would have been hard to do since it was written by many different authors over a large period of time but there are actually a lot of people that may not know that.
Some will argue that all translations are not exact due to language and culture differences which is true to a limited degree, however, the original Hebrew is believed to be completely inspired by God. When you examine the minor differences between languages and translations it still has no affect on the intended meaning.
While there are many branches of Christianity, Baptist, Methodists, Presbyterian and others, even those core churches contain different denominations. Different churches may have differences in belief such as baptism by immersion vs sprinkling, communion using grape juice vs real wine, musical instruments vs no instruments or even the King James version vs New American Standard, the central message, Jesus Christ is the same and should never change.
The Christian message is the need of mankind to have a way to pay for his transgression against the laws of God. The law stated the price was death but God loved mankind so much that He made a plan B, which was the substitution of Jesus Christ for us and all that was required of us was to sincerely accept it - THAT'S IT!
Of course, most other religions teach that man can work or earn their way to their god through man's own efforts and Christianity teaches that man cannot work or earn his way into heaven.
Manuscript Evidence. There are way more copies of the biblical manuscripts, with remarkable consistency between them, than there are for any of the classics like Plato, Aristotle, and Socrates.
Archaeological Evidence. Again and again, archaeological discoveries have verified the accuracy of the historical and cultural references in the Bible. The more they dig, the more confirmations that the Bible is infallible.
Eyewitness Accounts. The Bible was written by people who witnessed the events it describes; many were persecuted or martyred but never changed their story.
Corroborating Accounts. There are plenty of references in non-biblical sources to the events described in the Bible. The Jewish historian Josephus, born in 37 AD, “provide(s) indispensable background material for the student of…New Testament history.
Literary Consistency. The Bible contains 66 books written over 1,500 years by 40 different writers but it tells one "big story" of God's plan of salvation that culminated in Jesus Christ.
Expert Scrutiny. The early church had extremely high standards for what books were judged to be authentic and therefore included in the Bible. A book had to have been written by an Apostle or someone in their immediate circle, had to conform to basic Christian faith and had to be in widespread use among many churches.
Prophetic Consistency There are over 300 specific prophecies in the Old Testament that are fulfilled in the life, death, and resurrection of Jesus Christ in the New Testament.
Examples of Fulfilled Prophecy:
While there are a large number of prophecies in the Bible that were fulfilled just a couple of examples are stated in: Isiah 44:28 - 45:1-2 but also Daniel 9:24-27
Isiah 44:28 - 45:1-2 - A Prophecy of a King That Was Named By Name
This is a prophecy made about King Cyrus of Persia who came to the Persian throne in 559 BC and 9 years later unified the Medes and Persians after conquering the Medes. Cyrus is mentioned some twenty-three times in the literature of the Old Testament. Isaiah refers to Cyrus as Jehovah’s “shepherd,” the Lord’s “anointed,” who was providentially appointed to facilitate the divine plan. God would lead this monarch to “subdue nations” and “open doors” (an allusion to the Jews’ release from Babylonian captivity). He would make “rough places smooth,” i.e., accommodate the Hebrews’ return to their Palestinian homeland. He would ultimately be responsible for the rebuilding of Jerusalem and the reconstruction of the temple. The prophecy not only listed the details of what would occur but also named the king by name - Cyrus
"Seventy sevens have been decreed for your people. . . . So you are to know and discern that from the issuing of a decree to restore and rebuild Jerusalem until Messiah the Prince there will be seven sevens and sixty-two sevens; it will be built again, with plaza and moat, even in times of distress. Then after the sixty-two sevens the Messiah will be cut off and have nothing, and the people of the prince who is to come will destroy the city and the sanctuary.”
Exactly what is meant by “seventy sevens”? The phrase by itself is ambiguous, but taken in context the meaning is clear. Daniel’s prayer in verses 3-19 of the chapter refers to the fulfillment of a specific seventy-year period, the seventy years of the Babylonian captivity (as prophesied by Jeremiah). Daniel received the seventy sevens prophecy in response to his prayer. The prophecy foretold a period of seven times seventy yet to come, or seventy seven-year periods. Seventy seven-year periods equals 490 years.
The prophecy goes on to say that “from the issuing of a decree to restore and rebuild Jerusalem until Messiah the Prince there will be seven sevens (49) and sixty-two sevens (434). . . . Then after the sixty-two sevens the Messiah will be cut off and have nothing.”
Nebuchadnezzar had Jerusalem dismantled around 587 BC after having to put down two rebellions there in less than 10 years. At the time this prophecy was given, Jerusalem still lay in ruins. According to the prophecy, from the decree to rebuild Jerusalem there would be seven seven-year periods and sixty-two more seven-year periods—or 483 years—until the Messiah would show up. After the culmination of the 62 seven-year periods, or after 483rd year, the Messiah would be cut off.
Both the ancient Hebrews to whom Daniel was writing and the ancient Babylonians to whom he was subservient (the Book of Daniel having been written in Babylon during the latter half of the 6th century BC) used a 360-day year.
So, 483 years x 360 days = 173,880 days. This is the equivalent of 476 years and 25 days, using our modern Gregorian calendar’s 365-day year.
As for our starting point, the Persian emperor Artaxerxes Longimanus (who ruled from 464-424 BC) issued the edict to rebuild Jerusalem sometime during the Hebrew month of Nisan in the 20th year of his reign, or c. 445 BC (Nehemiah 2:1-8). From c. 445 BC, 173,880 days brings us to c. AD 30.
According to this prophecy, the Messiah would show up, present Himself as Messiah to the nation and then be “cut off” some time near AD 30. This was fulfilled as Jesus Christ presented Himself to the nation of Israel on Palm Sunday, was crucified on Preparation Day (the annual day on which the Passover Lamb was slain), and rose from the dead on Sunday.
The prophecy then goes on to say that, subsequent to the Messiah’s being killed, “the people of the prince who is to come will destroy the city and the sanctuary.” Within one generation of Christ’s crucifixion, Titus razed Jerusalem and destroyed the temple.
