What they DO AGREE ON is that you're basically NO GOOD and doomed to a life of hopelessness, despair, and eternal dammnaation unless you give them money and do what they tell you.
Believing that He died for their sins and rose from the grave does not save anyone UNLESS they understand (believe) that Jesus HAS given them eternallife (life with Him forever).
No one can enter eternallife in reality unless he is willing to give up his own centrality in order to find a true center in God and in a community of love.
