For our God is a consuming fire. Heb 12:29 For our God is a consuming fire. Our God is a consuming fire- His cleansing flame will burn away our dross and consume our flesh no matter how much it complains. In the old Covenant the freshly sacrificed flesh was tied to the horns of the altar so the muscles and nerves would not spam and flip it out of the fire. All this purification is repugnant to the flesh but sets our spirit free and causes us to walk in the light of His love.
