It seems rather circular to say that “good” in the Bible represents good, but in a general sense it’s true!
The case is this: The Lord is love itself given form and expression as wisdom itself, and that Divine Love and Divine Wisdom flow down into us, into the world and into the Bible in an unending stream with endless variety. Divine Love gives rise to our loves, our affections, our desires for good and the joy we can feel; Divine Wisdom gives rise to facts, knowledge, intelligence, understanding and human wisdom. And the more we can bring those two aspects of our lives into harmony, the more elevated we can become – which will in turn make us happier, more useful, and ultimately more angelic. And, of course, the more we turn away, the more truth becomes falsity and love becomes self-love. So this dance between the desire to be good and the understanding of truth is the driving force of human life, and almost everything in the Bible relates to it on a spiritual level.
When something is called “good” in the Bible, it is generally describing the highest, purest form of love possible in whatever spiritual state is being discussed. This is often summarized simply as “good” or as “charity” – which is a state of caring, or love to the neighbor.
