'I compare the troubles which we have to undergo in the course of a year - to a great bundle of sticks, far too large for us to lift. But God does not require us to carry the whole bundle at once. He mercifully unties the bundle, and gives us first one stick, which we are to carry today; and then another, which we are to carry tomorrow, and so forth. We can easily manage our troubles, if we would only carry the trouble appointed for each day. But the load will be too heavy for us - if we carry yesterday's burden again today, and then add the burden of tomorrow to the weight, before we are required to bear it.'
John Newton in Timothy Lane, Living without Worry: How to replace anxiety with peace, p.78.
