Dan Meyer, in his sermon "Why Remember the Passion?":

Years ago I traveled to Ecuador and spent a couple of weeks traveling in the mountains. The Quechua Indian people I met there lived amidst the most mind-numbing squalor. The disease and disfigured bodies were heartbreaking. The bugs and stench were everywhere. People were living in a hole in the ground and calling it a house. They were feeding on rotten food and prizing garbage as possessions. But they didn't know it. Why? Because everyone lived that way. They had never been given a picture of what it means to be a genuinely healthy human being. They did not know what an abundant life truly looked like.

That is our problem, too. It's the reason we think of ourselves as largely innocent people—people who have little to do with bringing about the Cross of Christ. We don't get how sick and undeveloped we are spiritually. In Psalm 14, David says that the one fully-healthy Being in the universe views the human race as we might view those Quechua villagers—only the gap between his life and that of our village is so much larger. "The Lord looks down from heaven on the sons of men to see if there are any who understand, any who seek God. But all have turned aside. They have together become corrupt. There is no one who does good, not even one." In other words, we are condemned, and we don't even know it.
