This great exhortation to prayer closes the passage on the Christian armour. Some even call it the seventh item of armour, but it is not part of the illustration.
Some people ask in the wrong way. Some charismatic friends have a way of commanding the devil out of someone: commanding this, commanding that; they take authority. That's not supplication. The supplicant is a beggar who crouches humbly, and he asked repeatedly for something he does not deserve. His answer will depend on the heart of the giver. It is a humble activity. Some people will go into a prayer meeting and they are eloquent people, and they will pray the most ornate prayers. That is not very humble. If you are eloquent, just subdue it for the prayer meeting. Earnest simplicity! We would rather there were no beggars, but whoever heard of a beggar who stood right up straight as a ramrod, and commanded, and with great eloquence swayed you by oratory?
You can watch the service of remembrance, you can see the clergy, eyes wide open, dressed up like princes, reading their prayers as though there is no personal participation, no personal identification with the prayer, in their highly ecclesiastical tone. Is that a prayer in the Spirit? Well, I wonder. Do you think they mean it? Is it a sincere prayer winged to heaven? Well, forgive me, but it doesn't look like it. Prayer in the Spirit means you are in earnest. You don't read that prayer; it comes from your heart and mind joined together, and you feel it.
