Recently I asked Christians at the Christian Forums website to fill in a checklist of all the requirements for heaven. The results show the great confusion on this issue. No answer was checked by more than 64% of the Christians. That answer, "Accept Jesus as personal saviour" is a very vague statement, with varying definitions of what it means, but still only 64% of the respondents think it is required. 58% said you need to believe in God, 42% said you need to confess Jesus with your mouth, and 50% said you need to accept Jesus as the Lord of your life. All of this from Christians who follow the same book! This is vivid testimony of the problems of living your life from a contradictory book like the Bible.
