But if our gospel is veiled, it is veiled only to those who are perishing

This refers back to what Paul said starting in 2 Corinthians 3:14. There Paul explained that there is a spiritual veil that prevents people from understanding when they read the old covenant. In the same way, people are not able to understand the gospel. (See: rc://en/ta/man/jit/figs-metaphor)

if our gospel is veiled, it is veiled

This can be stated in active form. Alternate translation: "if a veil covers our gospel, that veil covers it" (See: rc://en/ta/man/jit/figs-activepassive)

our gospel

"the gospel that we preach"
