The Bible provides me with the history and evidence of Jesus in terms of how he was born (Matthew 1:18-25), to whom he was born (Matthew 1:18-25), where he was born (Matthew 2:1-2), and when he was born (Matthew 2:1-2).
Then, John, provides the reason for Jesus' birth, John 3:16-21.
There are multiple eye witness accounts that confirm this information, and through the history of time, all that the Bible says has been confirmed. For me, this information convinces me that Jesus is who he said he was, the Son of God, and the Savior of the world and all mankind.
