...any one help me!? I have to bring in this object to represent this scripture here it is: And if men come unto me I will show unto them their weakness. I give unto men weakness that they may be humble; and my grace is sufficient for all men that humble themselves before me, for if they humble themselves before me and have faith in me, then will I make weak things become strong unto them. (Ether 12:6--from the Book of Mormon) I can't think of anything to represent strength or weakness. I was thinking maybe a battery--it can be weak and then you 'recharge' it and it's strong again, I don't know--please help! I need it by tomorrow-May 14 2010
