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])
