Why is God such a horrible salesman?

[Smilingfamily291]

God has the best product of all time (eternal life) and yet a ton more people will choose not to accept it. Today all it would take is a little update on the bible so its not so hard to read maybe a couple of miracles and boom you triple your followers. Its like god is on twitter he had a couple of good tweets but now he doesnt get on anymore but still expects a lot of followers come on!....i have a hard time wrapping my brain around if god is real then what is the point of creating man? It seems extremely cruel to create the world and create man and command them to worship him and if they dont then they will suffer for the rest of eternity... Also if god knows all and is in complete control why even go through the charade of life? He knows you will sin and go to hell and he still creates you? I tend to disagree with this point. In the bible it says that god gets upset with humans and decides to wipe them out ultimately changing his mind and sparing noah but i think by saying this it proves that maybe god doesnt know all or for whatever chooses not to? Theres a lot of things that dont seem to add up..,
