Blessed is the man that endureth temptation

Satan, in tempting, observes the temper and constitution. Satan will not tempt contrary to the natural disposition and temperament: he makes the wind and tide go together; whichever way the natural tide of the heart runs, that is the way that the wind of temptation blows.

Satan tempts to evil by them that are good; thus he gives poison in a golden cup. He tempted Christ by Peter. Peter dissuades Him from suffering. Master, pity Thyself. Who would have thought to have found the tempter in the mouth of an apostle?

If Adam in a few hours sinned himself out of Paradise, how soon would we sin ourselves into hell, if we were not kept by a greater power than our own! But God puts underneath His everlasting arms. Christian, canst thou not believe that evil which is in thy heart, and which will break forth suddenly, if God should leave thee? If God leave a man to himself, how suddenly and scandalously may sin break forth in the holiest of men on the earth! "I say unto all, Watch" (Mark 13:37). A wandering heart needs a watchful eye.

If you would not be overcome by temptation, be humble in your won eyes. They are nearest falling who presume on their own strength. The doves, says Pliny, take pride in their high flying, till at last they fly so high, that they become a prey to the hawk. So men when they fly high in pride and self-confidence, they become a prey to the tempter.

Satan doth not tempt God's children because they have sin in them, but because they have grace in them. Had they no grace he would not disturb them, for where he keeps possession all is in peace: "When the strong man armed keepeth his goods, his goods are at peace." A thief will not assault an empty house, but where he thinks there is treasure. Though to be tempted is a trouble, yet to think WHY you are tempted is a great comfort.
