The fact that God loves a sinner at all is itself a condemnation of her sin. Far from God's love for a sinner being God supporting the sins that make her happy or God accepting her together with her sins, if God loves her, that's the same as saying that He wants her out of her sin and with Him. God's Love is itself a condemnation of sin. Heaven is being wholly swallowed up by Divine Love. Those who go to Hell then, are those who close themselves off to Divine Love and won't let it possess them. They have found pleasure in their own desires and passions and reject Divine Love for that reason. Divine Love simply doesn't give them that same happiness, which isn't surprising, because it was never supposed to in the first place. Divine Love makes Himself present to help us overcome our passions and desires, build self-control, and live in Him in this life, that we might do likewise in the next. Worldly pleasures and passions are destructive of the end of eternal salvation, because that is the entire reason why the Devil promotes them with demonic passion in the first place.
Today we celebrate the feast of St. John the Theologian and at Vespers last night we heard from his first epistle:
"You are of God, little children, and have overcome him. Because greater is he that is in you, than he that is in the world. They are of the world: therefore of the world they speak, and the world heareth them. We are of God. He that knoweth God, heareth us. He that is not of God, heareth us not. By this we know the spirit of truth, and the spirit of error." (1 Jn 4:4-6)
Divine Love is in us. Self-serving passions are in worldly people. On one hand, what we possess is greater, so we will eventually defeat them. They are "playing from behind" because their master and their power is the inferior one. But at the same time, the two sides are mutually exclusive and will always be fighting one another, no matter how much they try to justify themselves by making up origins in God for their message.
