Verse 5. As long as I am in the world, &c. As the sun is the natural light of the world, even while it sinks away to the west, so am I, although my days are drawing to a close, the light of the spiritual world. What a sublime description is this! Jesus occupied the same place, filled the same space, shed his beams as far, in the moral world, as the sun does on natural objects; and as all is dark when that sun sinks to the west, so when he withdraws from the souls of men all is midnight and gloom. When we look on the sun in the firmament or in the west, let us remember that such is the great Sun of Righteousness in regard to our souls; that his shining is as necessary, and his beams as mild and lovely on the soul, as is the shining of the natural sun to illumine the material creation. See Barnes |Joh 1:4|.
