To some degree, there really is no spiritual meaning to the word “love” in the Bible. Why? Because if you truly love another, that is already a spiritual state. To put it simply, the Lord is Love Itself, a perfect and infinite love that is the source of all actual life and substance in the universe. Thus everything we are and everything we experience is a product of the Lord's love; there is no way for us to have any love from ourselves that is not ultimately the Lord's love, because the Lord's love is everything. When we feel love, what we're really doing is opening ourselves to be a conduit for the Lord's love -- truly a spiritual state. This also means that the more we can align our love with the Lord's love, the stronger our experience of love will be. The Lord's love is a constant desire to be conjoined with us, to be able to love us fully while protecting our right to choose. So the more we try to love that way, the more in harmony with Him we will be and the more powerful our feelings of love will be. In a general sense, then, most uses of “love” in the Bible represent a desire for union, connection, powered, and enriched by the Lord.

In Matthew 6:24, this signifies celestial of love. (Arcana Coelestia 3875[3])

In Malachi 2:11, this signifies to conjoin oneself with falsity. (Arcana Coelestia 4434[3])

2618. 'And Jehovah did to Sarah' means a state when the two existed united together - the Lord's Divine spiritual within His Divine celestial. This is clear from the meaning of 'doing', when it has reference to the Lord's Divine, as the entire realization of the effect and consequently of the state; and from the meaning of 'Jehovah', and also of 'Sarah', dealt with just above in 2616. As regards the state when the two existed united together - the Lord's Divine spiritual within His Divine celestial - this is the marriage itself of good and truth, which is the origin of the heavenly marriage. The heavenly marriage is the Lord's kingdom in heaven and on earth, and that is why so many times in the Word the Lord's kingdom is called a marriage, and is compared to a marriage. The reason, which is an arcanum, is that the marriage of Divine Good and Truth, and of Divine Truth and Good, within the Lord is the source of all conjugial love, and through that love the source of all celestial and spiritual love. What further arcana are embodied in these words - 'Jehovah visited Sarah as He had said, and Jehovah did to Sarah as He had spoken' - cannot be made known as they lie beyond description. For these words comprehend the state itself when the Lord's Divine exists united to His Human. Appearances of this state are presented by the Lord to the eyes of the angels by means of heavenly lights, and are illustrated also by means of indescribable representations. But those appearances cannot be presented to men because they would have to be presented by means of objects such as belong to the light of the world, which objects cannot serve to express them. Indeed a description that relies on such things makes them all the more obscure.
