We ALWAYS fall short; even you. ALWAYS, as in EVERY time. Your pride says you can be "good" enough; you can't. We all fall short of the glory of God; even you. God knows that, apparently you don't. Man can walk in ways he thinks are righteous, but will be left behind when God calls. Why? "I am good enough and can make it on my own"? YOU are not the ALPHA and the OMEGA; He is. He makes the rules and you don't like it so you have a snit.
Are you going to pitch a fit when He begins to separate the wheat from the chaff? What are you going to tell HIM? Assuming you can stop trembling, something like, "I was pretty good". Or maybe "Uh, I didn't know; nobody told me about your Son, and that all I had to do was ACCEPT Him as your generous offer to save a slug like me"? Too late; you've been put on notice. No man comes to the Father except through Jesus the Christ.
So what if you don't like it? You want to make the rules? Do you think you're wise enough? So go ahead and live by the golden rule; it's better than nothing, but remember that's the way YOU want to do it.
Peace,
