Do you remember where you were on September 11, 2001?  I will never forget where I was or what I was doing.  I was at North Cobb Christian School speaking in their chapel service to their elementary school students.  Three weeks before I had been asked to prepare a message on the omnipresence of God.  Not an easy task considering I was speaking to kindergarten through fifth grade. 
I remember thinking “How on earth am I going to take a concept like the omnipresence of God and get it on an elementary school level?” It is a lofty task to teach young children God is present everywhere at once.  There are some adults who have trouble grasping the concept. Fortunately, Scripture is very clear on the presence of the Lord in our lives.
Psalm 139:7-12 says, “Where can I go from Your Spirit? Where can I flee from Your presence? If I go up to the heavens, You are there; if I make my bed in the depths, You are there. If I rise on the wings of the dawn, if I settle on the far side of the sea, even there Your hand will guide me, Your right hand will hold me fast. If I say, ‘Surely the darkness will hide me and the light become night around me,’ even the darkness will not be dark to You; the night will shine like the day, for darkness is as light to You.” Jeremiah 23:23-24 says, “Am I only a God nearby,” declares the LORD, “and not a God far away? Can anyone hide in secret places so that I cannot see him?” declares the LORD. “Do not I fill heaven and earth?” declares the LORD.”
I was able to explain to them just because we don’t see God, doesn’t mean He isn’t there.  We don’t see electricity, but we see evidence of it.  When we flip a light switch, the light comes on for us.  We don’t see the wind, but we see evidence of it as the trees sway or our hair blows in our faces. They caught on quickly once I started giving them examples of things we experience, yet don’t see with our eyes.  The catch phrase for the day was, “Just like air, God is there!”
Who knew in the very moments I was teaching those precious students God is everywhere at all times, thousands of people would be clinging to that truth. God knew, that’s who. Family members who received goodbye phone calls from airplanes and twin towers testified to feeling His presence with them. Some of the survivors who made their way out of the buildings testified to feeling God directing them down the stairwells and out of the building to safety. God promises us in Scripture He will never leave us nor forsake us [Deuteronomy 31:6, 8, Joshua 1:5, Hebrews 13:5].  In order to make that promise, our Lord has to be omnipresent. 
What are you going through today?  Do you need the Lord with you? Call out to Him and He will answer you [2 Samuel 22:4, Psalm 18:3]. Remember, “Just like air, God is there!”
