“And the Lord went before them by day in a pillar of cloud to lead the way,  and by night in a pillar of fire to give them light. He did not take away the pillar of cloud by day or the pillar of fire by night from before the people.”
 
God made His presence apparent to His chosen people, the Israelites. It is the same today. When we focus on His presence, He makes it plainly clear He is with us by giving us His peace, through signs and wonders.
