The condition of being mortal and lacking ability, strength, or skill. Weakness is a state of being. All people are weak, and it is only by God's grace that they receive power to do righteous acts (Jacob 4: 6-7). This weakness is manifest in part in the individual weaknesses or frailties that each person has.

Strengthen ye the weak hands, Isa. 35: 3-4. The spirit indeed is willing, but the flesh is weak, Matt. 26: 41 (Mark 14: 38). Because of the weakness which is in me, according to the flesh, I would excuse myself, 1 Ne. 19: 6. I have been commanded to write these things, notwithstanding my weakness, 2 Ne. 33: 11. Do not be angry with thy servant because of his weakness, Ether 3: 2. The Gentiles will mock at these things because of our weakness in writing, Ether 12: 23-25, 40. I will show unto them their weakness, Ether 12: 27-28. Because thou hast seen thy weakness thou shalt be made strong, Ether 12: 37. He that is weak among you hereafter shall be made strong, D&C 50: 16. Jesus Christ knows the weakness of man, D&C 62: 1.
