Matthew 6:22

“The light of the body is the eye, etc.] Or, the “candle of the body is the eye”; for the eye is that in the body, as a candle is in the house; by the light of it, the several members of the body perform their office; and what is said of the eye of the body, is transferred to the eye of the mind: if therefore thine eye be single: that is, if thy mind be liberal, generous, and bountiful: for Christ is still upon the same subject of liberality, and against covetousness; and here speaks entirely in the language of the Jews, who could easily understand him; in whose writings we read of three sorts of eyes; a good eye, a middling one, and an evil one; so in the offerings of the first fruits f432,…”

“The light--the lamp. of the body is the eye: if therefore thine eye be single--simple, clear. As applied to the outward eye, this means general soundness; particularly, not looking two ways. Here, as also in classical Greek, it is used figuratively to denote the simplicity of the mind's eye, singleness of purpose, looking right at its object, as opposed to having two ends in view. (See Pro 4:25-27). thy whole body shall be full of light--illuminated. As with the bodily vision, the man who looks with a good, sound eye, walks in light, seeing every object clear; so a simple and persistent purpose to serve and please God in everything will make the whole character consistent and bright.”

“The light of the body ... - 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 steadily toward 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 in order to correct and regulate action. Rope-dancers, that they may steady themselves, fix the eye on some object on the wall,…”

“The eye is the lamp of the body - And what the eye is to the body, the intention is to the soul. We may observe with what exact propriety our Lord places purity of intention between worldly desires and worldly cares, either of which directly tend to destroy. If thine eye be single - Singly fixed on God and heaven, thy whole soul will be full of holiness and happiness. If thine eye be evil - Not single, aiming at any thing else. Matthew 6:24”

“6:22 Your eye is like a lamp: It gives light to the body and so enlightens the entire person. • Healthy means morally healthy, with simple, wholehearted devotion to God (6:24). Here it connotes generosity.”
