What attribute of God do atheists fear most?
Is it his omniscience, omnipotence, or omnipresent?
God's omniscience: I know the destiny of every living thing.
God's omnipotence: My power is fathomless
God's omnipresence: You cannot hide from me, buddy. Even though thou shall ignore my existence, I am still aware of your every action.
God's love: Could it possibly be his love? Yes, love does require emotional vulnerability, and that would demand atheists to reciprocate, which they cannot do because of pride and fear. It's normal to fear rejection, but God is love and doesn't have a bias.
