I cannot see wind, but I know when it's around. I cannot see air, but I am sure of it.
I spent part of Sunday in a park, snapping pictures of trees and new spring blossoms. Intent upon capturing close-up shots of early dogwoods, I didn't give much thought to what might be above me. Until I heard the sound of distant laughter.
Turning to look up, I saw the wind.
"Bless the Lord,O my soul! O Lord my God, you are very great! ....who makes the clouds your chariot, who rides on the wings of the wind...." (Psalm 104:1 & 3)
