A Formidable Foe

How does this battle picture representation? How is David a type of Christ as the conqueror for the salvation of His children? How is Saul a picture of flesh that would not fight the battle for his people do to fear? Who are the evil men spoken of? Who is it that teaches the heart of Christ? How does children's books muddy the water of the Gospel? How is faith objective, always concerning Christ? How is the Gospel used for correction and reproof and instruction in righteousness? How does Goliath represent the flesh? Is this battle the battle of the elect church or of Christ? How is it a mystery that His children only pray to be forgiven because they already are forgiven? How did Christ defeat Satan with Satan's own sword?
