The commandments all boil down to two; 1) love God with all your heart, soul, and mind, and 2) love your neighbor as yourself. God tells us how to love Him, 1) do justice, 2) love kindness, and 3) walk humbly with him.
If you accomplish the first commandment you will accomplish the second through justice and kindness. Many today simply believe loving your neighbor is what Christianity is all about. But this fails in fulfilling the first command.
OK, that is all good, however, HOW do I love God, How does He want me to show my love for Him? How do I love my neighbor, what does God say it means to love my neighbor, and for that matter, who does God say is my neighbor?
Unless one knows the answer to the question, how does God define love, so to be able to put that love into action, there is absolutely no evidence that one even loves God r his neighbor is there not?
