Though I walk through the valley of the shadow of death I will fear no evil.
The Psalmist states this quite clearly. He will walk through the valley of the shadow of death. The promise isn't that we'll be kept from that valley, but that in our journey through that valley we will be comforted by the presence of God. And yet, as I walk through my own valley of dark shadows, I do fear evil. Not the external evil of some demonic force "out there" but of the evil within me. I fear my self sabotage, my self destructive impulses that are consistently more clever than my rationality or even my faith. With one hand I dig trenches under my own foundations and with the other I try to shore them back up. Meanwhile the valley descends and keeps getting darker. I know valleys don't go on forever, but when you're in the middle of one, it can sure feel that way. And feeling can be more powerful than any rational understanding. I will believe against my feelings that God's presence and care are with me. It's my only hope.
