"I will instruct thee and teach thee in the way which thou shalt go :i will guide thee with Mine eye. Be ye not as the horse, or as the mule, which have no understanding :whose mouth must be held in with bit and bridle lest they come near unto thee " (vers. 8, 9).
Now we are often like the horse, or the mule, every one of us; and this, because our souls have not been plowed up. When there is anything in which the will of man is at work, the Lord deals with us as with the horse or the mule, holding us in. When every part of the heart is in contact with Himself, He guides us with His "eye." "The light of the body is the eye:therefore when thine eye is single, thy whole body also is full of light; but when thine eye is evil, thy whole body also is full of darkness. Take heed therefore that the light which is in thee be not darkness. If thy whole body therefore be full of light, having no part dark, the whole shall be full of light, as when the bright shining of a candle doth give thee light" (Luke 9:34-36). When there is anything wherein the eye is not single, so long as this is the case there is not free intercourse in heart and affections with God; and the consequence is, our will not being subdued, we are not led simply of God. When the heart is in a right state, the whole body is "full of light," and there is the quick perception of the will of God. He just teaches us by His "eye" all He wishes, and produces in us '' quickness of understanding in the fear of Jehovah," hearts without any objects save the will and glory of God. And that is just what Christ was:'' Lo, I come:in the volume of the book it is written of Me, I delight to do Thy will, O My God:yea, Thy law is in My heart" (Ps. 40:7, 8; Heb. 10; 7). Where there is this, it may be bitter and painful as to the circumstances of the path, but there is in it the joy of obedience as obedience. There is always joy, and the consequence-God guiding us by His eye.
