The contradiction that you have foun out is true, but there are also other points about that, Mark Bible says it not to be the fig/fruit season, so that Jesus could not find any fig on the tree. That it is of course quite normal not to find fruit on a tree before the season of giving fruit reaches. Bibles themselves bring their Christ an infair, unjust one. Secondly, the apostle amazes at that point and upon that Jesus tell them that they will be able to do more powerful acts such as changing a mountains place by ordering the mountain. as he curses the tree though it was not the fig season yet, the Christ of the Bibles also mean that the power of faith is something given to harm people...
Lastly, Christians claim Jesus pointed Jews by that act, cause as to them Jesus is the Judge, then that shows how right Jews were in killing Jesus of the Bibles, cause he is an unjust one....
