Summary: Israel in the wilderness was blessed when they followed God’s cloud by day and pillar of fire by night. We in the New Testament era can likewise incur great blessings by “following the cloud” of God’s presence, purposes, and guidance.
Exodus 13:17-22 …[18a] So God led the people around by the desert road toward the Red Sea….  After leaving Succoth they camped at Etham on the edge of the desert.  By day the Lord went ahead of them in a pillar of cloud to guide them on their way and by night in a pillar of fire to give them light, so that they could travel by day or night.  Neither the pillar of cloud by day nor the pillar of fire by night left its place in front of the people.
