Consider the weak and seemingly despicable means and weapons that God employs to overthrow Satan. Christ poured the greater contempt upon Satan in the victory that he obtained over him, by reason of the means of his preparing himself for it, and the weapons he hath used. Christ chooses to encounter Satan in the human nature, in a poor, frail, afflicted state. He did as David did. David when going against the Philistine refused Saul's armor, a helmet of brass, a coat of mail, and his sword.
