Would you sell one of your eyes for a million dollars? How about both eyes for ten million? No one in their right mind would! Your eyes are precious to you... but they are only a "window" for your soul. Your soul (your inner being, your life, your personality) looks out through those eyes. Consider how precious your eyes are... then realize that Jesus said that Hell is so horrible that you would be better off tearing out your own eyes than ending up there for all eternity (Mark 9:43-48).
Do you know what God did so that you wouldn't have to spend eternity in Hell?
