The best evidence of God's presence is the devil's growl. So wrote good Mr. Spurgeon once in "The Sword and the Trowel," and that little sentence has helped many a tried and tired child Of God to stand fast and even rejoice under the fiercest attacks of the foe.
We read in the book of Samuel that the moment that David was crowned at Hebron, "All the Philistines came up to seek David." And the moment we get anything from the Lord worth contending for, then the devil comes to seek us.
When the enemy meets us at the threshold of any great work for God let us accept it as "a token of salvation," and claim double blessing, victory and power. Power is developed by resistance. The cannon carries twice as far because the exploding power has to find its way through resistance. The way electricity is produced in the power-house yonder is by the sharp friction of the revolving wheels. And so we shall find some day that even Satan has been one of God's agencies of blessing.
