just to name a few.
It is my testimony that 'these things will give thee experience and shall be for thy good' (D&C 122)
Our older brother Satan wanted to take away our freedom and force us to make the right choice.
Our older brother Jesus said He would come to earth, to be our Savior so that our Father's plan could be upheld and through His atonement we would have a chance to repent of our wrong choices.
So here we are on earth and we are indeed free to choose. When someone does something bad to someone else, like the recent shootings in Colorado, some may ask "Where was God?" Doesn't he care about those poor people?
