John 3.16-21 was today's Gospel reading at Mass. Here's verse 16: God so loved the world that he gave his only-begotten Son, so that everyone who believes in him might not perish but might have eternal life. You've probably heard this verse quoted and seen it on billboards so often that you don't think about it much anymore. To think about it, it is a declaration of the most beautiful truth of critical importance to us! We should really know it by heart and think about it often. Here are verses 19-20: And this is the verdict, that the light came into the world, but people preferred darkness to light, because their works were evil. For everyone who does wicked things hates the light and does not come toward the light, so that his works might not be exposed. Here we have the "sickness" of the world clearly diagnosed by the Apostle John just about two thousand years ago.
