By Judges 15 the life of Samson is a contradiction of God's blessing & spiritual power in a man who is impulsive, unteachable, and driven by his own fleshly desires.
Samson is living by the mantra, "As they did unto me, so have I done unto them..." In Samson we have the example of the lust of the flesh, so what does it mean to "walk in the Spirit", and how is it possible?
