The habit of turning to God...

And perhaps, as those who do not turn to God in petty trials will have no habit or such resort to help them when the great trials come, so those who have not learned to ask Him for childish things will have less readiness to ask Him for the great ones. We must not be too high-minded. I fancy we may sometimes be deterred from small prayers by a sense of our own dignity rather than of God’s.

This was from a Mockingbird (March 7,2012) quote of C.S. Lewis' Letters to Malcolm Chiefly on Prayer.
