Sorry, may not be complex, but I don't think theology needs to be.
Welcome one more to the love camp. Big surprise!
Micah 6:8
Luke 10:27
Matthew 5:1-48
I'd put forth that we can define God in variable terms- many ways for us puny humans to talk about the Divine. I see my faith as being more about practice. This practice is pretty clear. Matthew 5 is no big mystery.
I am also of the opinion that love is pretty well defined. Biblically, the Greek lays out the different types of love and makes it clear what is meant once you understand agape. Furthermore, I believe this is written on every person's heart. We know when we are in the presence of a supremely loving person. We know when we are giving someone the gift of love without strings attached. We know when we are forgiving, as opposed to when we are faking it. It's really not difficult at all to discern. In every moment we can ask ourselves: Am I, in this moment, living in a way to heal and not to hurt?
I think that question applies to all living beings, including ourselves. We should give ourselves the same love, kindness, compassion, and forgiveness we give to everyone. Then we will be able to reach out to others from a place of calm and peace, and a place of mutual understanding.
Anyhoo, there's my bare minimum, extrapolated a bit for the sake of clarity.
Love boundlessly, selflessly, and with total abandon in joy.
