2 Corinthians 4:18

while we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal. [We have here the same law for the Christian which governed the life of Christ (Philippians 2:7-11). If afflictions are viewed with regard to temporal affairs, they seem heavy and profitless; but when we look upon them as part of God's discipline which prepares us for an unseen world, then they seem light and momentary. In proportion as we keep our eyes upon the future kingdom of God, with its glorious circumstances and modes of existence, our afflictions increase our faith and enlarge our character, and so work out for us a more glorious future. The phrase "eternal weight" suggests a royal garment, richly freighted with ornaments of gold and jewels. Trapp quaintly observes, "For affliction, here's glory; for light affliction, a weight of glory; for momentary affliction, eternal glory."]
