Mark Batterson's powerful book Wild Goose Chase-in Scotland

Celtic Christians had a name for the Holy Spirit-An Geadh-Glas, or the Wild Goose. The name hints at mystery. Much like a wild goose, the Spirit of God cannot be tracked or tamed. An element of danger, an air of unpredictability surround Him. And while the name may sound a little sacrilegious, I cannot think of a better description of what it's like to follow the Spirit through life.
