2 Corinthians 4:18 - Ellicott's Commentary On The Whole Bible

While we look not at the things which are seen. — The “while we look” is, according to the Greek idiom, the condition of what had been stated in the preceding verse. The “look” is that of one who contemplates this or that as the end or goal for which he strives. The “things that are seen” are, of course, all the incidents and circumstances of the present life; the “things that are not seen” (the very phrase of Hebrews 11:1) are the objects of faith, immortality, eternal life, the crown of righteousness, the beatific vision. These things are subject to no time-limits, and endure through all the ages of God’s purposes. The others are but for a brief season, and then are as though they had not been. Striking as the words are, they find an echo in the words of a contemporary seeker after wisdom: “These things (the things which most men seek after),” says Seneca (Ep. lix.), “are but objects of the imagination, and present a show of being but for a time... Let us give our minds to the things which are eternal.”
