I've seen a lot of strengthening of my faith through learning here as well. I have an actual concept of the creator, which was before based upon the issues I suffered in childhood.
Your translated saying is similar to one of the sayings in my scriptures- 'Therefore be perfect as your Father in heaven is perfect'. ;) Matthew, I think?
(Not that there isn't allowance for time to overcome imperfections, but neither is there progression in wallowing in inaction!)
Much of the same is reflected in Eastern thought, though I admit much of the material in holy writings are harmful when viewed through a western-trained brain. It is too easy to twist something a bit too much toward the pick-it-apart-to-it's-elements and use-only-the-parts-you-like mindset. The easiest path being the preferred path.
Cheers and bless, and here's hoping you have some fresh sunshine!
PS, I'm trying to find the 'Ultimate treasure collection' you refer to. Is it a blog post, a link on your user profile..?
