Did brother Jesus cursed the fig tree, did he need timber for his furnace; Jesus wept?

I think the cursing of the fig tree is a parable to teach us that all things serve a purpose. The tree was barren so was NOT serving it's purpose. The tree was planted, it grew, but it had no fruit, so was therefore, useless. So it is with people. If we serve no purpose, we are useless. There is another bible verse that goes along well with this parable. "Faith, without works, is dead".
