(36) If thy whole body therefore be full of light.--The statement reads at first like an identical proposition. "If thy whole body be full of light, it shall be full of light all over." The apparent truism is, however, the most expressive utterance of a truth. If the "whole body"--life in all its various manifestations--is illumined by the divine light; if the character is in its measure perfect, as that of the Father is perfect, who is Light, and in whom is no darkness at all (1John 1:5); if passion, prejudice, ignorance are no longer there--then that character is . . ." We expect to hear something else as a climax of praise, but there is no higher word possible; the whole character is "full of light," illumined, flooded by the eternal Light.

Verse 36. - 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. The Lord here completes his allegory, still preserving the same images, with a sketch of the condition of a holy and humble man of heart, who with a "single eye," that is, honestly, trustfully, lovingly, has looked upon the sign and believed. Godet's comment on this hard and mystic saying of the Blessed is very beautiful: "When, through the fact of the clearness of thine eye, thy whole body shall be penetrated with light, without there being in thee the least trace of darkness, then the phenomenon which will be wrought in thee will resemble what takes place on thy body when it is placed in the rays of a luminous focus. Jesus means that from the inward part of a perfectly sanctified man there rays forth a splendor which glorifies the external man, as when he is shone upon from without. It is glory as the result of holiness. The phenomenon described here by Jesus is no other than that which was realized in himself on the occasion of his transfiguration, and which he now applies to all believers." There is little doubt that this teaching had been spoken by the Master on one, if not on more than one, previous occasion. In St. Matthew's report, in almost identical language (Matthew 5:15 and Matthew 6:22), the immediate application was different, and the reference of the lamp put in a prominent place was not to the Resurrection.

11:29-36 Christ promised that there should be one sign more given, even the sign of Jonah the prophet; which in Matthew is explained, as meaning the resurrection of Christ; and he warned them to improve this sign. But though Christ himself were the constant preacher in any congregation, and worked miracles daily among them, yet unless his grace humbled their hearts, they would not profit by his word. Let us not desire more evidence and fuller teaching than the Lord is pleased to afford us. We should pray without ceasing that our hearts and understandings may be opened, that we may profit by the light we enjoy. And especially take heed that the light which is in us be not darkness; for if our leading principles be wrong, our judgment and practice must become more so.If thy whole body therefore be full of light,.... That is, if the whole soul, as the Ethiopic version reads, be full of Gospel light, through the illuminating influences of the blessed Spirit accompanying the word:

having no part dark; every power and faculty of the soul being affected with it, and influenced by it, though, as yet, the light and knowledge of evangelical things is not perfect in any:

the whole shall be full of light, as when the bright shining of a candle doth give thee light; the whole soul shall be as full of light and joy, which the Gospel always brings with it, as a room is full of light, when a candle is lighted, and shines brightly, and burns clearly in it.
