The word of the Lord is flawless and impenetrable.  The word of God and belief in God is not a crutch as some people would say it is, but rather is a shield that can protect us when we are too weak to face certain trials.  It also strenghtens us to be ready to go out and battle evil.  "...He (God) is a shield for all who take refuge in him." -Psalm 30b. -Pastor Mike
