The 25,000+ manuscripts for the New Testament were written less than two hundred years after Jesus’ death. These numbers are significant because nowhere near this number of manuscripts exists for any other ancient work, and any manuscripts that were written within two hundred years are considered reliable by most scholars. Especially notable is the short time in which Paul wrote his epistles—some scholars granting that some, potentially all of them, were written less than just forty years after Jesus’ death. Additionally, ancient historians and writers, such as Roman Tacitus, Suetonius, Flavius Josephus, Lucian of Samosata, and Pliny the Younger, seem to refer to Jesus Christ or His followers. Lastly, it is notable that the prophecy Jesus gave in Matthew 24:1-2 about Israel’s holy temple being destroyed came to pass in AD 70 when the Romans utterly decimated it, which points to the validity of Jesus Christ’s existence and even His divine nature.
Typically, when people demand historical evidence of Jesus' existence, they mean evidence "outside of the Bible." However, the Bible is a reliable historical source of evidence for Jesus’ existence, especially because nothing in the Bible has been discredited by secular historians. Today, followers of Jesus are seeing the end time prophecies written in His Book, the Bible, unfold before their eyes (1 Timothy 4:1-5; 2 Timothy 3:1-5, 4:3-4; 2 Peter 2-3). Those who follow Jesus have experienced His existence in the form of a personal relationship with Him (John 1:12, 3:1-21) and the transforming power of that relationship. Christians through the centuries have been so influenced by this relationship that they have willingly and gladly become martyrs. This began with Jesus' early followers, who had previously shared life with Him during His earthly ministry. Many of these followers were stoned, beaten to death, burned at the stake, and boiled in oil—they were willing to because they had personally known and put their faith and belief in the very real person of Jesus Christ.
