Any blank surface can become a place for prayers.

“The Lord will guide you continually, and satisfy your needs in parched places, and make your bones strong; and you shall be like a watered garden, like a spring of water, whose waters never fail.”  (Isaiah 58:11 NRSV)

P.S. This is not ME! I saw a woman at Virginia Theological Seminary and asked if I could take a picture. She said she also combines Prayer, Play, and Art.
