One of the biggest obstacles in the way of people coming to Christianity is that they think they know about it already.
Timothy Keller[T]he main problem in life is sin, and the only solution is God and his grace. The alternative to this view is to identify something besides sin as the main problem with the world and something besides God as the main remedy. That demonizes something that is not completely bad, and makes an idol out of something that cannot be the ultimate good.
