A 9 year old boy shares his testimony of the Book of Mormon.
Where we lack, He makes up the difference. Where we sink, He buoys us up. Where we fail, He prevails. He is our Champion.
And also, ye yourselves will succor those that stand in need of your succor; ye will administer of your substance unto him that standeth in need; and ye will not suffer that the beggar putteth up his petition to you in vain, and turn him out to perish. Mosiah 4:16
He who humbly follows Jesus Christ will experience and share in His light. And that light will grow until it eventually dispels even the most profound darkness. ~Dieter F. Uchtdorf
