What kind of prayer will cause somebody to utter rubbish for one hour? It is madness. You do not need too much words to communicate to the heavens, if you allow your inner self to take hold of you during prayer. I also think that encouraging communicants not to marry outside RCCG, amounts to religious commercialization towards achieving selfish ends. Neither too much prayer nor teachings of the Pastors, Bishops, Reverends, e.t.c,  will take one to eternal bliss of Heavenly Kingdom; rather the undiluted truth from the word of God.
