2. The fire is surrounded with a glory: A brightness was about it, in which it enfolded itself, yet it made some discovery of itself. Though we cannot see into the fire, cannot by searching find out God to perfection, yet we see the brightness that is round about it, the reflection of this fire from the thick cloud. Moses might see God's back parts, but not his face. We have some light concerning the nature of God, from the brightness which encompasses it, though we have not an insight into it, by reason of the cloud spread upon it. Nothing is more easy than to determine that God is, nothing more difficult than to describe what he is. When God displays his wrath as fire, yet there is a brightness about it; for his holiness and justice appear very illustrious in the punishment of sin and sinners: even about the devouring fire there is a brightness, which glorified saints will for ever admire.
