Babak, that is a decision you must make for yourself, but do not follow blindly simply because it is in a book, or because others say it is so....
I follow no God, and do not believe in a Creator or Deity.
I read the Message of Jesus Christ, because whoever he was, whatever he did, his words and actions were wise, and apply as much today as they did then....But I do not worship him as a saviour....
Everything I hear and see, I consider, weigh up, think about and cogitate on...
I take nothing at face value - blindly, without research.
Once I am satisfied, one way or the other, then, I begin my walk again....
