We read in the book of Second Samuel that the moment David was crowned at Hebron, "All the Philistines came up to seek David in full force but David went back to the stronghold.” At the moment we get anything from the Lord worth contending for, 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. In the powerhouse, electricity is produced by the magnetic resistance of the revolving armature. Even so we shall find some day that the devil’s attack or resistance has been one of God's agencies of blessing. Rejoice and count it a blessing when we are tried.
James 1:2 - 4
Dear brothers and sisters, when troubles come your way, consider it an opportunity for great joy. For you know that when your faith is tested, your endurance has a chance to grow. So let it grow, for when your endurance is fully developed, you will be perfect and complete, needing nothing.
