The man who has his mouth full of arguments in prayer will soon have his mouth full of benedictions in answer to prayer.
Dear friend, do you have your mouth full right now? What of? Full of complaining? Pray to the Lord to rinse that black stuff out of your mouth, for it will little help you, and it will be bitter in your bowels one of these days.
Oh, have your mouth full of prayer, full of it, full of arguments, so that there is room for nothing else.
