In 2 Corinthians 3:6, Paul introduces the new covenant of the Spirit that gives life — the basis for the greater glory of the permanent covenant in 3:11.

In 2 Corinthians 3:7, Moses' fading face illustrates the old covenant's transient glory, which 3:11 generalizes into a principle.

Because the new covenant is permanent and more glorious (3:11), Paul declares in 4:1 that he does not lose heart — the logical result.

2 Corinthians 4:4 reveals Satan blinds minds to the gospel's glory — the lasting glory contrasted with the fading glory of the law in 3:11.

Hebrews 8:13 directly states the old covenant is obsolete and vanishing, reinforcing 3:11's claim that the old was passing away yet had glory.
