I used to pray that God would feed the hungry, or do this or that, but now I pray that he will guide me to do whatever I'm supposed to do, what I can do. I used to pray for answers, but now I'm praying for strength. I used to believe that prayer changes things, but now I know that prayer changes us and we change things – Mother Teresa.
Pray. Pray for the strength to help others. Do it every day. Then go out and use your renewed power to change things for the better as God showed you and chose you to do.
Trust in the LORD with all your heart, and do not lean on your own understanding. In all your ways acknowledge Him, and He will make straight your paths.
