The light of the body is the eye: if therefore your eye be single, your whole body shall be full of light.
The light of the body is the eye. Different versions give "lantern," or "candle," or "lamp." Then the idea is, that the aim and purpose a man has in life will be like a light shining on all his life and work and relations. If the aim be a high and noble one, it will brighten and ennoble all his doings. If it be a low and ignoble one, it will discolour and degrade all his doings. Or, to take another view: a man's aim in life will be like the eye, through which he comes into relation with everything. If it be clean and healthy, everything is seen as it is. If it be impure and diseased, it is as if a man saw everything through coloured glasses. Then the anxiety of a Christian disciple should concern fixing the right aim, settling the one supreme purpose of life. Christ says our aim should be "righteousness." We do but put the same thing in another form when we say it should be Christ-likeness. "Singleness of intention will preserve us from the snare of having a double treasure, and therefore a divided heart." The question to press on attention is - What are you living for?
I. NOTHING. There are thousands of persons who are just living on, they know not and care not how or why. Enough for them is the butterfly-life of self-indulgence. Neither whence they came, nor what they are here for, nor whither they are going, troubles them in the least. And theirs is but as the life of the "dumb, driven cattle," who have no "uplooking eyes."
II. SOMETHING LOW AND POOR. Such things as wealth for wealth's sake, position for position's sake, power for power's sake. A soul has but a low aim who only asks, "What shall we eat? what shall we drink?" and lets the "lust of the flesh, the lust of the eyes, and the pride of life '" decide what his aim shall be.
III. SOMETHING NOBLE FROM HUMAN STANDPOINTS. The world has its heroes in all its spheres. We may fix on one, find his aim, and make it ours, and let it inspire us to noble things.
IV. SOMETHING DIVINE. Here show that God has been pleased to come into our human spheres, in the Person of Jesus Christ, that he might make himself our inspiring and sanctifying aim. - R.T.
