Prayer is a strong wall, and a fort of the church; it is a godly Christian’s weapon, which no man knoweth nor findeth, but only he who hath the spirit of grace and of prayer. The three first petitions in our Lord’s prayer do comprehend such great and celestial things, that no heart is able to search them out. The fourth petition containeth the whole policy and economy, or the temporal and house-government, and all things necessary for this life. The fifth prayer striveth and fighteth against our own evil consciences, against original and actual sins, which trouble the same, etc. Truly they were penned by wisdom itself; none but God could have done the like. We cannot pray without faith in Christ the Mediator. The Turks, the Jews, and the ungodly may rehearse and speak the words of prayer after one, but they cannot pray. And although the Apostles were taught this prayer by Christ, and prayed often, yet they prayed not as they should have prayed: for Christ saith, “Hitherto ye have not prayed in my name;” whereas, doubtless, they had prayed much, and spoken the words. But when the Holy Ghost came, then they prayed aright in the name of Christ. If praying and reading of prayer be but only a bare work, as the Papists hold it to be, then the righteousness of the law is nothing worth. The upright prayer of a godly Christian is a strong hedge, as God himself saith, “And I sought for a man among them that should make up the hedge, and stand in the gap before me for the land, that I should not destroy it, but I found none,” etc. Therefore, said Luther, when others do blaspheme, let us pray. David saith, “He doth the will of them that fear Him, and heareth their prayers.” _That we must daily go on in Praying_. I, said Luther, have every day enough to do to pray. And when I lay me down to rest, I pray the Lord’s Prayer, and afterwards take hold on two or three sentences out of the Bible, and so betake myself to sleep, then I am well satisfied. _That Preachers ought to join their Prayers together_. Dr. Aepinus, Superintendent of Hambrough, coming to Wittemberg to speak with Luther, who, after his dispatch, and at his taking leave, said, I commend myself and our church at Hambrough to your prayers. Luther answered him, and said, Loving Aepine, the cause is not ours, but God’s: let us join our prayers together, as then the cause will be holpen. I will pray against the Pope and the Turk as long as I live: and I like it well that you take such course at Hambrough, earnestly to pray against Mahomet and the Pope. _Of the Power of Prayer_.
