From ancient times, philosophers have summed up the human condition as a quest to answer three fundamental questions: What should I do? What can I know? What can I hope for?
In response to the common-sense comment of doubting Thomas, Jesus Christ gives us the definitive answer to each one of these questions when he tells us that he is the way, the truth, and the life.
Actually, Jesus doesn't just give the answers; he is the answers. "I am the way" can translate into: "What should you do? Follow me! Do what I have done."
"I am the truth" means: "What can you know? You can know everything, if only you know me.
"Knowing me, more and more every day, you know the secret behind the workings of the whole universe and the deepest yearnings of the human heart, because I made them both. I am the eternal Word, the very Wisdom of God."
"I am the life" means: "What can you hope for? In me, through me, you can hope for the fullness of life that you long for in the very depths of your soul. "You can hope for your very own room in my Father's house, in heaven - I have gone to prepare it for you. "In my Father's house all sorrows turn to joy, all weakness turns to strength, and life grows more alive as eternity unfolds.
Christ is truly the living water that quenches every thirst. He is truly the light that scatters every type of darkness. The quest of every man and woman to satisfy the heart's deepest needs is the quest to seek his face.
As St Augustine famously wrote, "Our hearts are restless until they rest in God." And Jesus Christ is God.
