I think, Niki, that, when Christians are saying that one's eternal soul is at risk, if one does not believe and trust in God / Jesus / the word of God, etc, it is important to make it known that the book upon which we are supposed to rely for this 'truth' is not (always) reliable.
The Bible is the infallible word of God (supposedly). The New Testament tells us all about Jesus. Jesus is the Redeemer (supposedly), and, if we do not believe, we (supposedly) suffer eternal hell and damnation.
Yet, the book of God's word
, which tells us all about his redeeming son, is full of contraditions and other inexplicable content.
Therefore, this should be considered a very serious matter.
Of course, if none of it is true, then it hardly matters at all
