Jesus weeps over the city of Jerusalem, not because they're going to reject Him and crucify Him, but because they missed their chance to actually experience peace. Jerusalem means: city of peace and yet they're not experiencing true peace because they're rejecting the One who can give it to them. I think we all battle with this in one way or another in our lives. We have things we think will make us feel great, fulfilled, happy, secure, and Jesus says to us, "if only you knew what would actually help you." We want our students to take Jesus up on the opportunity to turn away from those things and turn to Him, and not experience the disaster that sin brings about in and through their lives.
