Charles Spurgeon Commentary Luke 12:24-25

"Consider the ravens, that they sow not, neither reap; which have no store-chamber nor barn; and God feedeth them: of how much more value are ye than the birds! And which of you by being anxious can add a cubit unto the measure of his life?" — Luke 12:24-25 (ASV)

For they neither sow nor reap; which neither have storehouse nor barn; and God feedeth them: how much more are ye better than the fowls? And which of you with taking thought can add to his stature one cubit?

"You cannot lengthen your body;" or perhaps the Savior meant, "You cannot lengthen out your life."
