I think that focusing on that helps us to better deal with the challenges we face. Most people would not break the law if they absolutely knew they were going to be caught. Likewise a person who understood that they would be richly rewarded if they could just go through a series of hard things would do all the could to gain that reward.
I feel very blessed to have the faith I do and to have such hope in things to come. It helps me to endure and to focus on what is really important.
