Doing The Best We Can
"It is not a cure or a comfort to simply say [the standards] do not matter. We all know they do matter, for all mankind is 'instructed sufficiently that they know good from evil' (2 Nephi 2:5).
"If we are doing the best we can, we should not become discouraged. When we fall short, as we do, or stumble, which we might, there is always the remedy of repentance and forgiveness."
(Boyd K. Packer, "A Defense and a Refuge," Ensign, Nov. 2006, 86)
Great quote.
I think that this applies to All of our Father's Children of all faiths and backgrounds. That is why someone who does not have the teachings of the gospel, but lives his or her life to the best of their knowledge is blessed. That is why we have been counselled not to Judge others harshly, because another person may be doing the best they can with the circumstances that they are living in. And that is why those who have been given more must try to live up to the standards that we have been taught.
God is merciful and I believe he will judge us much better then we judge others or even ourselves.
