I can say that came to atheism late in life... It was a gradual and long journey for me but I made it. Unfortunately, I raised my children believing in Christianity (what I thought it was correct at the time). Now they are adults and cannot understand why I am an atheist, My parents are also orthodox Christians and sometimes it is tense when family is together. My question is how you tell your adult children that you were wrong? How you deal with elderly Christian parents that think you are going to hell for your lack of faith?
