Not only does our prayer deflect the enemy, but our purity deflects the enemy. God calls you to purity because He wants your heart protected and at rest, inhospitable to the devil and his intentions. God wants you full of power and confidence and spiritual vitality. He wants you free to bless and encourage others, to receive and celebrate His goodness, to become such a stick-of-dynamite prayer warrior that Satan just hates hearing your coffee pot heat up in the morning.
