'Temptation is carried out in three ways, by suggestion, by delight, by consent,' by the suggestion of the enemy, or by the delight, or even by the consent of our frailty. But if even at the enemy's suggestion we are unwilling to take delight in or to consent to sin, temptation itself carries us on to the victory by which we may deserve to win the crown of life.
