God came as man came, and tried that, they pounded 3 spikes into His body, and was crucified! Men don't want to give up their measily power, and riches. So, been there, done that already! Didn't work so well.God already knew what would happen, He had it written before He got here, kinda gave man a heads up, still didn't get it!
Because most are selfcentered and won't open up to a discussion like that. There is a religion similar to what you seem to be asking for and it is called Ba'hai. you should look into it.
