Your question:
Possibly there is another path which leads to love - ever increasing levels. The missing part to the "bible" puzzle may NOT be that we understand that we should love BUT that we are not taught HOW TO LOVE the unlovely
Possibly this path is not in conflict with the bible but not contained within its pages.

Answer: Maybe the real problem is a lack of communication with those reading the Bible, such that they are unable to understand because they have Rejected God?
For God has Promised those who Seek him diligently and are willing to change shall be shown the Truths about Love etc!
