In these pages written over half-a-century ago, Nicolas Corte gives you incontrovertible proof that Satan exists, that he and his legions of devils assault you daily, and that by means of relentless attacks overwhelming and subtle they intend to corrupt you, damn you, and drag you into Hell along with those you love and all the rest of mankind.

A grand battle is raging right now for the future of your soul: not an abstract battle of ideas and principles, but a tough, personal struggle that pits God and you against Satan and his minions. Worse: the nearer you grow to God and the closer to victory, the greater are the traps the Devil lays in your path.

With God's help and the help of the good angels, who are truly your friends and guardians you can repel the Devil; but to succeed, you must first come to understand Satan's devious ways and recognize his subtle paths of attack. Armed with that knowledge, which Nicolas Corte gives you here, you'll soon be able to identify temptations early and equip yourself to repel them long before they grow strong enough to overthrow you.

Soon, the Devil's trials will cease to be for you occasions of sin, becoming instead (as they did for scores of saints) providential opportunities for genuine spiritual victories.
