If we just worry about the big picture, we are powerless. So my secret is to start right away doing whatever little work I can do. I try to give joy to one person in the morning, and remove the suffering of one person in the afternoon. If you and your friends do not despise the small work, a million people will remove a lot of suffering.
I saw before me a huge crowd which no one could count from every nation and tongue. They stood before the throne and the Lamb, dressed in long white robes and holding palm branches in their hands...They said, Amen! Praise the glory, wisdom and thanksgiving and honor, power and might to our God forever.
