Comments on Alma 32:21 specifically relating to hope.
Many individuals do not even try to develop faith because they do not even hope for these things to be true. People around the world may not even hope for the ability to live with God for eternity, to resurrect to a perfect state, to live with their families forever, etc. Why then, would they even want to have faith in the possibility of these things? An important part to gaining faith is to ignite a spark in people so that they will hope for these things to possibly be true, thus leading to faith. Ultimately, when we are able to help others get this spark of hope, they will then have to work on their own by planting the word in their hearts and developing the faith therewith. Once hope and faith are absolute, they can partake of the fruit from the tree of life in their own lives.
