Passage
For which cause we faint not: but though our outward man is corrupted, yet the inward man is renewed day by day.
For which cause we faint not: but though our outward man is corrupted, yet the inward man is renewed day by day.
2 Corinthians 4:14 Knowing that he who raised up Jesus will raise us up also with Jesus and place us with you.
2 Corinthians 4:15 For all things are for your sakes: that the grace, abounding through many, may abound in thanksgiving unto the glory of God.
2 Corinthians 4:16 For which cause we faint not: but though our outward man is corrupted, yet the inward man is renewed day by day.
2 Corinthians 4:17 For that which is at present momentary and light of our tribulation worketh for us above measure, exceedingly an eternal weight of glory.
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.
The verse centers on "cause", "faint", "though", "outward", "corrupted", "inward", and "renewed". It is saying that the verse draws attention to "cause" and "faint", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 15's "For all things are for your sakes..." into verse 17's "For that which is at present momentary...", so "cause" and "faint" belong inside that flow. In 2 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "cause" and "faint" with trust shaped by these words, not by a vague optimism outside the passage.
