Satan does not want you to be a persistent, methodical, importunistic believer who lives by prayer. He doesn’t want you to be so disciplined and tenacious in prayer that once you begin to pray, no matter how long the answer is delayed, he has no hope of winning.
If we had more Christians who prayed like that, then there would be an inevitable, unstoppable, step-by-step, day-by-day dismantling of the kingdom of darkness that he could never withstand. The end of his kingdom of bondage, disease, deformities, and emotional torment would be written on the wall.
Satan is quite content to keep Christians thinking that all the big things are in God’s hands alone, so they never need to worry about more than their own needs and those of their immediate family. (The Art of War, p. 31)
You must learn to live by prayer—to be a tenacious, persistent, and stubborn believer who prays without ceasing. May God make you a champion of prayer—a prayer-warrior—who never surrenders until victory is won. There is nothing more effectual than the faith-filled prayer of a believer.
Ephesians 6:18 AMP: Pray at all times (on every occasion, in every season) in the Spirit, with all [manner of] prayer and entreaty. To that end keep alert and watch with strong purpose and perseverance, interceding in behalf of all the saints (God’s consecrated people).
