...and because there was so large a crowd to start Christianity get off to a flying start is why missionaries.Nah, there have always been missionaries and crusades to carry on.
How has anyone demonstrated that Jesus was resurrected? Just because people believe a thing, doesn't make it true. There aren't any eyewitness accounts. We're talking about people in a story.
But to say that people don't die for "something that was not true" is demonstrably false. For instance, how about that religious cult that drank all the Kool-Aid and committed suicide? They certainly seemed to believe in the thing they were dying for (and killing their children for).
That's not really relevant to the discussion, but I don't agree that we should "not resist an evil person." I think evil should always be resisted.
Crusades were a teaching outside of 1st-centrury Christianity done by fake 'weed/tares' Christians.
Yes, there are local fake 'weed/tares' cults but they don't spread their beliefs on an international scale.
Jesus taught the 'good news' (Not bad news) of God's kingdom (Daniel 2:44) would be proclaimed world wide.
Yes, evil should be resisted.
Jesus will Not only resist evil (remember when twice Jesus threw out those corrupted money changers out of the temple). The coming 'sword-like executional words from Jesus' mouth' will rid the Earth of the wicked.
Just as taught at Isaiah 11:3-4 & Revelation 19:14-15 will come to pass. Just as it is written so shall it be !
