Hebrews 12:23,24 (KJV)
23 To the general assembly and church of the firstborn, which are written in heaven, and to God the Judge of all, and to the spirits of just men made perfect,
24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.
God And His Angels Are A Consuming Fire
God and His angels are a consuming fire. The difference is in their brightness, as angels are sons of God.
