a Bible passage
18because we look not at what can be seen but at what cannot be seen; for what can be seen is temporary, but what cannot be seen is eternal.
18. look not at—as our aim.
things … seen—"earthly things" (Php 3:19). We mind not the things seen, whether affliction or refreshment come, so as to be seduced by the latter, or deterred by the former [Chrysostom].
things … not seen—not "the invisible things" of Ro 1:20, but the things which, though not seen now, shall be so hereafter.
temporal—rather, "for a time"; in contrast to eternal. English Version uses "temporal" for temporary. The Greek is rightly translated in the similar passage, "the pleasures of sin for a season."
