2 Corinthians 3:18: Beholding His Glory
Paul describes a real sight of the Lord's glory, but an indirect one, like a reflection rather than a photograph. Those who see it are changed into the same image by the Lord, the Spirit.
Transformed by Beholding Christ's Glory
Paul locates real change not in self-scrutiny but in sustained looking at Christ. The unveiled face is given; the transformation is the Spirit's work, moving from glory to glory.
