Unlike the Israelites who could not see God's glory reflected on Moses's face because he had covered it with a veil, there is nothing to prevent believers from seeing and understanding God's glory. (See: [[rc://en/ta/man/translate/figs-metaphor]])
The Spirit is changing believers to be glorious like him. This can be stated in active form. Alternate translation: "The Lord is transforming us into his same glorious likeness" (See: [[rc://en/ta/man/translate/figs-activepassive]])
