christianity is a very confusing religion ..
there are too many holy books, the Bible, The Trinity, The Old Testament,Gospel According to Matthew ,Old Testament ..
Which book you should believe ..

the only book we must believe in as muslims is the Quran .. that's the reason for islam being simple and peaceful ..

((Allah is the only god .. if you disagree you will go to the hell ..))

this is written in our quran ..And i believe in it

lastly .. everybody has the right to believe in what they believe in ..
