Does God work all things for good?

How many of your earthly cares would cease if you would give their due weight to the saying—

Cast all your care upon God for He careth for you or would take to heart the Saviour's warning against anxiety? 

It is really necessary to assure you that such words of God are quite true—that the hairs of your head are really numbered—that all your affairs are open to the eye of God and that it is His holy and gracious will to make all things work together for your good.
