Each one of us likes either Peach Cobbler or applie pie, if that is the only choice we have. If the desserts are world wide, there are plenty of choices including these two. There is no rhyme or reason why any one likes one over the other.
If a doctor, dietician, nutritionist, connoisseur, scientist or your mother tries to explain one tastes better than the other, you would still eat what appeals to you? Whatever one is conditioned or nurtured (convert) with, it becomes a part of one. Faith has no rhyme reason logic or any grounding to it, it is just faith.
Let me enjoy my peach cobbler and you enjoy your apple pie, both give the pleasure to each others senses, is there a problem with it? Each faith gives tranquility to the one it is part of both nature and nurturance. As the beauty is in the eyes of the beholder, I say, faith is in the heart of the believer.
