Matthew Chapter 6, Verse 22
From BibleWiki
22: ο λυχνος του σωματος εστιν ο οφθαλμος εαν ουν ο οφθαλμος σου απλους η ολον το σωμα σου φωτεινον εσται
22: The light of the body is the eye: if therefore thine eye be
single, thy whole body shall be full of light.
22: The light of thy body is thy eye. If thy eye be single, thy whole
body shall be lightsome.
The light of the body, etc. The sentiment stated in the preceding verses - the duty of fixing the affections on heavenly things - Jesus proceeds to illustrate by a reference to the eye. When the eye is directed singly and steadily towards an object, and is in health, or is single, everything is clear and plain. If it vibrates, flies to different objects, is fixed on no one singly, or is diseased, nothing is seen clearly. Everything is dim and confused. The man, therefore, is unsteady. The eye regulates the motion of the body. To have an object distinctly in view, is necessary to correct and regulate action, Rope-dancers, in order to steady themselves, fix the eye on some object on the wall, and look steadily at that. If they should look down on the rope or the people, they would become dizzy and fall. A man crossing a stream on a log, if he will look across at some object steadily, will be in little danger. If he looks down on the dashing and rolling waters, he will become dizzy, and fall. So Jesus says, in order that the conduct may be right, it is important to fix the affections on heaven. Having the affections there - having the eye of faith single, steady, unwavering - all the conduct will be correspondent.
Single. Steady, devoted to one object. Not confused, as persons' eyes are when they see double.
Thy whole body shall be full of light. Your conduct will be regular and steady. All that is needful to direct the body is that the eye be fixed right. No other light is required. So all that is needful to direct the soul and the conduct is that the eye of faith be fixed on heaven, that the affections be there.
