Agape Love
Agape love is the unconditional and unwavering support given to all of the universe, by the universe itself. Such love cannot be broken, nor fail because it is given by the very same entity that receives it. That then, is our task, our path forward. To love all creation as ourselves.
To be one with God then, must mean that. To love like he does. To love all things equally. As you love yourself, knowing it to be yourself.
Consider for a moment, what it means to be a bad person. The word person, is a derivation of the word persona, which means a role, or a mask. A mask may be bad, evil, a sinner. But the one wearing the mask, is entirely untainted by the mask it wears. That which is behind all creation, is God. Unconditional love. Agape love.
It loves all the masks, all the personas and it can never not love it, because its very essence is that love.
