Creation, by God, was uniformly good until, by creating a single man, He created loneliness. Loneliness had not existed from eternity until then. God had always existed in His triune perfection, and so for the first time God said “it is not good.” Therefore society and relationships are a necessary part of the human existence. “It is not good for man to be alone.”
Love is not an emotional state, it is a choice and an action. God loved the world so much that His only Son died for us: for you and for me. I guarantee the nails driven into His hands and feet and the spear driven into his side did not just tickle.
