36. People who have separated faith from love do not even know what faith is. When they do entertain an idea about faith, some of them see it only as mere thought, others as thought directed towards the Lord, and a few as the doctrine of faith. But faith involves not only knowledge of all the things that the doctrine of faith embraces and the acknowledgment of them; it is first and foremost obedience to everything that doctrine teaches. The primary point that it teaches for men's obedience is love of the Lord and love of the neighbour. Whoever is devoid of this is devoid of faith, a point which the Lord teaches so plainly in Mark as to leave absolutely no room for doubt,

The first of all the commandments is, Hear, O Israel, the Lord our God is one Lord. Therefore you shall love the Lord your God with all your heart, and with all your soul, and with all your mind, and with all your strength. This is the first commandment. The second is also like it, You shall love your neighbour as yourself. There is no other commandment greater than these. Mark 11:28-33.

In Matthew, He calls the former 'the first and great commandment', and says 'on these commandments the Law and Prophets depend', Matthew 22:35-40. The Law and the Prophets are the doctrine of faith in its entirety and the whole of the Word.

The sun in the Bible represents the Lord, with its heat representing His love and its light representing His wisdom. “Daytime,” then, represents a state in which we are turned toward the Lord, receiving His love and being enlightened by His truth. And “nighttime,” obviously, represents states in which we are turned away from the Lord, left cold and blind to the truth. The most common word used for it in the New Christian theology is “obscurity.” The darkness is not absolute, of course. The light of the moon represents the understanding we can have based on facts and our own intelligence. But while the moon reflects some of the sun's light, it offers almost no heat, so this kind of understanding is a cold one, without the warmth of love. And at its darkest and coldest, night represents a state of judgment. This happens when a person -- or a church -- becomes so mired in evil and falsity that there is no light or heat. The Lord can then step in, separate the good from the evil, consign the evil to hell and begin rebuilding based on the remnant that is still good. Drastic as that sounds, it is something that we all go through repeatedly in various aspects of our loves, so that we can be rid of what is evil and let the Lord rebuild us as angels.
