Christians don't believe that goodness gets you to heaven. Christians believe it's exhausting to rely on your own goodness to please God.
Timothy KellerThe human heart is an idol factory that takes good things like a successful career, love, material possessions, even family, and turns them into ultimate things. Our hearts deify them as the center of our lives, because, we think, they can give us significance and security, safety and fulfillment, if we attain them.
Timothy Keller
