To see God's all consuming fire must have been a sight. Both glorious and terrifying I suppose. The Israelites had seen God's power before with the plagues and parting of the sea. But fire is in w sense magical on its own. To watch God's fire consume the offerings is a reminder that his love consumes our sin and his anger can consume the lost.
Lord, I pray I never anger you to the point of seeing your wrath, and that you consume my sins out of love. Amen.
