Locate and show them the place in the Bible that states If one prays with hate, selfishness,... the prayers will Not be answered! Also if they pray to anyone one or anything other than GOD no answer!
The Catholic religion tells people that they can pray to any angels in Heaven and anyone that has already died. Yet the Bible states When one dose so, they are very severely Sinning!
the bible God claim we are selfish so he doesn't answer us -.-

I will said back to him in the bible God has so many expectations 1 He want you to repent 2 He want you to has faith and follow him 3 He want u to has patience 4 He doesn't want you to put anyone first or idols first 5 He want u to listen to him 6 If I loose faith than blame me .. If God exist I think actually he is the evil one where he claim Satan is Evil A Evil Person who will claim another person is Evil or like Pot Calling Kettle Black
