Faith is a belief in something, together with a level of assurance that that something is true. Faith = Belief * Assurance.
Hope is desire for some occurrence or goal, together with a belief that that outcome will happen. Hope = Desire * Faith'.
Because hope involves a type of faith, hope cannot exist without faith. Also, faith will not drive us to action if we do not have a desire for the outcomes we believe will result from our action. Thus, faith must be accompanied by hope to produce action.
Both God's and Satan's armies are constantly working to influence the beliefs, desires, and assurances of each person. For instance, Satan would have us hope for coercive power and fulfillment of selfish lust. He attacks the surety of our beliefs in personal responsibility and good works. Heavenly Father entices us to believe His guidelines and believe them more deeply. He helps us feel the value of good works so our desire to do them increases.
Though both sides constantly invite and entice us, neither side will force our mind. We choose our faith and hope every day.
