God is love, pure, and all good, and omnipotent? In my opinion, if someone says, "God is" or "God is not" or "God looks like" or "God doesn't look like" they've limited him and he's no longer omnipresent, omnipotent, or omnificent.

So then, how can God be omnipotent and be limited to only love?  Love cannot be hate.  Good cannot be evil.  The light cannot be on and off at the same time.  Schrödinger's cat is dead or alive but not both.

"only God understands how this can be" is not a valid answer.

1 John 4:8


  Whoever does not love does not know God, because God is love. 


But does that mean, he is only love?
The assertion that God's omniscience, omnipresence, and omnificence somehow means that God must be everything is false.  God's omniscience means God knows all things.  God's omnipresence means that God is everywhere present.  God's omnificence means that He has all creative power.  None of these mandate that God must be both love and evil.  

God is certainly not everything.  He is holy--not unholy.  He is just--not unjust.  He is good--not evil.  He is infinite--not finite.

God is truly indescribable, though, in that He cannot be completely defined by words.  Indeed, I'm not sure any person could be completely described by words, even as finite as we are.

God created the physical universe of time, space, and matter, so He is completely outside of those things--beyond space, beyond time, and matter--and is not limited by those things.  Yet, again, that does not mean He is everything--or everyone.  He is only Himself and not His creation.

As an aside, hate is often misunderstood as the opposite of love.  However, apathy seems to be a better candidate for this.  The fact that one does not love a particular person does not necessarily mean he hates the person.  He may not know the person at all, so he would be apathetic towards him.
