 Scriptures:

Alma 10:5

 5 Nevertheless, after all this, I never have known much of the ways of the Lord, and his ^amysteries and marvelous power. I said I never had known much of these things; but behold, I mistake, for I have seen much of his mysteries and his marvelous power; yea, even in the preservation of the lives of this people.

As long as the reason of man continues fallible, and he is at liberty to exercise it, different opinions will be formed.
James Madison

I've always very earnestly tried to do my best, so I just have to trust that and forgive myself for being fallible.

Personal Definition:
I think fallible means Liable to screw up sometimes. We are all fallible, but the happy thing is, we can repent! Sometimes things we do, might just be plain right out wrong, and we might or might not realize it, but if we do, we can clean up and start out new by taking advantage of the atonement. I think it's a fantastical concept!  And I'm very grateful for it!
