If one believes in a God, then why did God send "his son" ...
Logic error. Does not follow from premise. Many religions have no such cop-out.
If god is an omnipotent, etc etc etc,know it all, then s/he is responsible for creating "sin" in the first place, and the only reason to have a convoluted mechanism to "earn freedom" from this imposed sin is to impose a Stockholm syndrome behavior on the believers. Control.
One has only to look at the denial of reality that is necessary to believe ... sound more like devil worship to me.
Enjoy
