It must be true

If it’s not true, how can this be:

Over two thousand years later and we’re still talking about Him. He commanded no great armies to spread His word by the sword. He had not a powerful navy to ensure His access to high places. He had no money to speak of to buy allegiances and fund His journeys. He was not a great political figure of His time. He led no great political movement. He was no rebel standing against government authority. Quite the contrary, He asked followers to render unto Cesar that which is Cesar’s. He gained and maintained a following not for what He gave to them but rather for what He asked of them.

Yet 2,000 years later, we still celebrate His birth, study His life, mourn His death and accept His resurrection as the basis of our belief.
