"The secret of Christian quietness is not indifference, but the knowledge that God is my Father, He loves me, I shall never think of anything He will forget, and worry becomes an impossibility.
It is not so true that "prayer changes things" as that prayer changes us, and then we change things. Consequently we must not ask God to do what he has created us to do. For instance, Jesus Christ is not a social reformer, He came to alter us first, and if there is any social reform to be done on earth, we must do it. God has so constituted things that prayer on the basis of redemption alters the way we look at things. Prayer is not altering things externally, but working wonders within our disposition." - Oswald Chambers 2 Corinthians 5:17
