Quite often we feel like camels, whose burden seems too much to bear. We complain of the weight and want it lifted off. Some of us lay down when it feels heavy and refuse to move another step. Other camels trust that the weight will not hurt them. It may be hard, but it is good practice for carrying other loads in the future.
However, if you keep with it, after a while you will bear that burden with ease. The proverbial straw that breaks the camel's back is not added when your back is week, but after it is stronger. And then more weight is added, which in turn makes us stronger- to which a point will eventually come in which we can bear all things, and our back was never broken.
However, for the camel that felt the weight and laid down in despair or refusal, his back was indeed broken by the heavier load, because he never allowed himself to be strengthened to bear it.
D & C 78:18 Ye cannot bear all thing now. (notice the now part) and know that The Lord said "I will lead you along."
