That's already been addressed: We don't "need" it.
Still I see threads on FR asking for prayers. I see Paul telling us to intercede for others, and asking others to intercede for him. Do you think Paul thought he "needed" the prayers of the Ephesians? Did he think God's arm was too short? Did he want something other than God's will to be done?
Isnt God going to be insulted?
He was insulted at Calvary. He is insulted by every sin I commit. I put all my trust in His forgiveness, or, rather, I ask Him for the grace to do so more and more until one day He brings perfect trust from me.
So since God has already been insulted, just carry on, is that it?
