[Serious] Could an omnipotent and omniscient god prove that he was God?

[tjdisc]

I think the whole "belief" thing is overstated.  I don't think it's so much if we believe He exists (demons do and that doesn't do so much for them).  It's whether you want to be like Him or not.  Loving, kind, merciful, long-suffering etc.  All the fruits of the Spirit.  We can't be truly - that's why He died.  To provide a way to pull us out of the depraved karmic debt/hole we can find ourselves in.  To give us a path to be like Him that we weren't capable of before.  I'm not going to say you can't be perfect.  Jesus said He came for the sick, not the healthy.  If you can return love for hate and exemplify all the fruits of the Spirit, then you HAVE chosen Him in spirit and in truth, whether you believe He exists or not.
