Some people have found that using Bible verses in their prayers is an effective way to pray. “Praying Scripture back to God” seems to help to focus the mind and to assure that the subject matter of the prayer is pleasing to God.
James 5:16 says, “The effectual fervent prayer of a righteous man availeth much” (KJV). First John 5:14–15 says, “This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us. And if we know that he hears us—whatever we ask—we know that we have what we asked of him.” The word effectual means “sufficient to produce a desired result.” Fervent means “constant, strenuous, and intense.” James and John are both telling us that for our prayers to be effective, they must be fervent, meaningful, and in agreement with the will of God.
One way to know that our prayers are the will of God is to pray specific Scriptures that express what is in our hearts. Scripture should not be used as some kind of magic chant, repeated mindlessly as though the words themselves had power. The power of prayer comes from God alone to a heart that is “fervent.” But when we find a command or promise that expresses what is in our hearts, we know we are agreeing with God when we use it as a prayer. It is, after all, His Word. The more we memorize and meditate on the Bible, the more it becomes part of us. The truth we have studied comes to mind when we are praying and is often the answer we are seeking. Often, when we don’t know what to pray, Scripture can give us the words. The Psalms contain hundreds of prayers, and many of them have already put our thoughts into words.
