I have met countless times brothers and sisters that believed there was no hope for them or that they are not worthy to be in the truth. The reasoning behind it is usually that they committed horrible sins, causing them to feel condemned. On the other hand it is common to find people that feel they are saved already or that they are in good graces with the Heavenly Father while ignoring completely their sins. Those have to be brought back to reality and realize the consequences of their actions otherwise they will be punished. Both could learn from a fallen king by the name of Manasses. As he said, “in me thou wilt shew all thy goodness”. You will find that you are in fact Manasses.
