If we feel ourselves qualified to sit back and judge the prayer requests we hear, and spurn those who "do not know how to pray as they ought," we place ourselves above the Spirit. He may condescend to intercede for us when we pray imperfectly, but we have higher standards than He does, evidently. "Don't bother me with the details, and don't bother me without the details. Tailor your requests to suit me, or you can forget my prayers."
Oh, how I thank God that He never spurns my imperfect prayer requests, because those are the only kind I've ever made! And not only does He not reject our requests, but He actually goes a step farther and polishes them up for us, making them like sweet incense as He brings them before the Father.
Are we above interceding...above taking an imperfect request and agreeing with it by offering an imperfect prayer of our own? Do we not realize that the Holy Spirit will have to clean up our intercessory prayers, just as He has to clean up the prayers of the person we're interceding for?
Do we not realize it is a privilege to be allowed to pray for others, to be allowed the opportunity to be used by God in someone else's life, when we are so imperfect ourselves?
What is the purpose of asking for prayer? Is it, as my acquaintance suggested, because we lack faith to believe that God hears us if we pray alone? Is it so that people can judge our requests and determine if we deserve their intercession? Why didn't God just tell us to keep our requests to ourselves, and why did He tell us to pray for one another?
Could it be that, wonder of wonders, God wants us to learn to love one another, humbly and non-judgmentally? And could it be that love is actually more than enjoyment of others, but extends into bearing with them, and bearing their burdens?
What would these acquaintances of mine do, I wonder, if someone they deeply loved offered a "sub-par" request, with either too much or too little detail? Would they roll their eyes and say, "Forget it, I'm not praying for you?" I think not...and the reason would be simple. They love that person. So when they roll their eyes and refuse to pray for someone else with a "sub-par" request, with too much or too little detail, the reason is equally simple. They do not love that person.
Jesus said that "Love your neighbor" is the second-greatest commandment.
