Our God is a consuming fire‪.‬ Malachi - God's Messenger.

For ye are not come unto the mount that might be touched, and that burned with fire, nor unto blackness, and darkness, and tempest,
And the sound of a trumpet, and the voice of words; which voice they that heard intreated that the word should not be spoken to them any more:............

..........But ye are come unto mount Sion, and unto the city of the living God, the heavenly Jerusalem, and to an innumerable company of angels,
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, And to Jesus the mediator of the new covenant,
