This chapter is such an incredible, fearful image of the throne of God. I cannot help but be stunned to think of what this vision must have been like. How frightening! For those of us who have believed in Christ, this is the great and glorious God we serve. He should be feared, but with a reverential fear, not a fear that causes us to shrink back. And the only reason we don’t shrink back from this all-consuming fire of glory is because of the blood of Christ. In Christ, the Son of God, we are totally accepted by God the Father, by faith in Christ.
While God is loving, kind, merciful, gentle and all of those other things, He is also at the same time just, righteous, and full of wrath against sin, unrighteousness and all wickedness, because all of it is a slap in His face on an infinite level, because His worth and value are infinite. He must punish all wrong-doing.
