3 In those days came John the Baptist, preaching in the wilderness of Judaea, 2 And saying, Repent ye: for the kingdom of heaven is at hand. 3 For this is he that was spoken of by the prophet Esaias (Isaiah), saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make his paths straight (Matthew 3:1-3).
Many of the Old Testament prophecies had their fulfillment in the New Testament. So many prophecies in fact that it would be impossible to make them all up. Additionally, there were eyewitnesses still alive at the time of the writing of the New Testament accounts that could have verified the authenticity of the accounts. Furthermore the authors and the apostles all died a martyr’s death (except for John) and it is unlikely that they would die for a known lie. There are also accounts of some of the New Testament biblical participants in literature outside of the New Testament. For example, John the Baptist is mentioned in the works of Josephus. Josephus was a Jewish historian (not a Christian) that wrote around the time of the compiling of the New Testament accounts. God's providence and foreknowledge of these events is clear, and the evidence from the Old and New Testament that Christ is the Son of God is so compelling that if we disregard the testimony we do so in spite of the evidence.
