In human history, there have been many big heros. But Jesus was just a son of an ordinary family.
Why so many people still remember him? Why so many people are still reading bible?
In 1970s, my family had quite a few Mao's books although my parent are just farmers. Now how many people are still reading Mao's books? Maybe Xi Jinping is still reading them in order to learn the evil tricks to control Chinese.
When Jesus was alive, he only had some coward type of disciples, no knives, no soldiers. Why he is still alive in many people's heart?
When Mao was alive, he had millions of soldiers. Now how many people still keep him in heart as a dear leader?
In 10 years, I am sure that Xi Jinping will go to a garbage can and his dogs will run away. But Jesus will be still alive in many people's heart.
Hope this helps.
