I may say that I believe in absolute truth, but do I? or do I just believe in my perception of it.
Most believers can agree on, or at least not dare to disagree on many plain and to the point scripture such as the first , sixth, seventh and eighth commandments, but there are much disagreement about the fourth commandment and the other ones are hardly mentioned.
I believe we can ignore any thing an atheist may say so while there is an absolute truth a Christian`s concern should be just what is the truth on any given subject in scripture?
What you SAY is less important than what you do. My opinion only.
