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])

801. This description of these people before the Flood shows the nature of the style used by the most ancient people, and consequently of the prophetical style. From here down to the end of this chapter these people are described, in the present verses as regards their persuasions, and in verse 23 that follows as regards their desires. That is, they are described as regards the state of the things of their understanding, and after that as regards the state of those of their will. Although the proper things of the understanding and of the will did not exist in them, the things in them that were the reverse of these must nevertheless be called things of the understanding and will. Though in no sense things of the understanding, persuasions of falsity must be called such because they are matters of thought and reasoning; and the same applies to desires which are in no sense things of the will. Those people are described, as I say, first of all as regards their persuasions of falsity, and after that as regards their desires. This is the reason why verse 23 which follows repeats, though in a different order, the things referred to in this verse 21.

[2] Such also is the prophetical style, the reason being that there are two kinds of life with man - the first belonging to things of the understanding, the second to those of the will - which are very distinct and separate from each other. Man is composed of both, and although they are separated in man nowadays, they still flow one into the other and for the most part unite. The fact that they unite, and how they do so, could be established and illustrated in many ways. Since man is therefore composed of these two parts - understanding and will - and one flows into the other, the Word when describing man describes each part separately, which is the reason for repetitions; otherwise the description would be defective. As with the will and understanding here, so with everything else. It is their subjects that make things exactly what they are. Being the product of their subjects, they are attributes of those subjects. Things separated from their subject, that is, from their substance, are not anything. This is the reason why when the Word describes something it does so as regards both areas. In this way the description of everything is made complete.
