Hope

I really believe that hope is the one idea that I am most passionate about.
The world can be a bleak, scary place.  Things happen for no good reason all the time and often times those things are painful.
Hope is the belief that God is kind and that He will fulfill his promises, and it changes everything. It changes the focus from the details of the here and now to the meaning which those details have in the big picture.  Most of the things which I and the rest of humanity tend to worry about are not that significant even the scope of a human lifetime, let alone eternity.
What it means that God will fulfill His promises is that everything will eventually be fair and just, that our lives will be given meaning, and that we will live forever in this just and meaningful life.  That is awesome! Even the worst aspects of earth life will be made up.  There will be no sickness, death, physical or mental weakness, hunger, etc.

According to my beliefs as a Latter-day Saint (Mormon) every single human being who has ever lived, or ever will, will be resurrected and given immortality free from physical problems. This gift is a freebee which Christ has given to all of humankind regardless of the way they have chosen to live. The gift of Eternal Life, or the kind of life that God Himself has, is promised only on condition of repentance and honest effort to live the way Jesus Christ did while He was on earth. That means allowing Him to teach, guide, and instruct you in the way you live.
So hope changes everything.

If God does not exist or will not fulfill those promises then we will all live out our years however we decide to live them, and when we die, our self-created purposes and meanings will die with us. Even a well remembered name will last only so long before it is forgotten and lost.

However.

If  an honest God will honor these promises then the meaning of this life is eternal and every injustice on earth becomes nothing more than a temporary inconvenience which will be made up in the end
