Second Corinthians 4. Verse 16 to 18. So, we do not lose heart. Though our outer self is wasting away, our inner self is being renewed day by day. For this light momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal. This passage acknowledges the reality of human suffering and physical decline, but contrasts this with the renewal and growth happening within us. The “light momentary affliction” is portrayed as preparation for a future “eternal weight of glory,” revealing that present difficulties have a purpose in shaping us for a glorious, everlasting reality beyond our current comprehension. This message is significant for providing hope and strength, reminding us to prioritize spiritual growth and eternal truths over temporary challenges and the material world.
