Part of what I love about Christianity, and part of what separates it out from every other worldview is its view of the incarnation, the fact that God became flesh and lived among us. What is perhaps most astonishing about that doctrine is the historic teaching of just how God lived among us. He didn't live a celebrity life of ease and comfort, nor did He live a separated life of abstract philosophical pontification, but rather took the form of a suffering servant and entered into the thick and thistles of human suffering to experience it fully with His people.
Gideon was the same weak man, the people were still in their same immediate difficult plight, but the reality of God's presence changed the prospects of God's people. The promise of God's power, changed the potential of God's chosen servant. Gideon stepped into the reality of being a mighty man of valor not by changing who he was, but by remembering who he was with, and more significantly, who was with him.
