I should examine all my actions, taking Jesus as my model and example. What a vast difference between my prayer and His; between my use of time, my way of speaking, walking, dealing with others, etc., and that of the child Jesus! If I could only keep Him before my eyes always, my life would be far different from what it has been.

COMMENT: The incarnation was one of the central moments of history, and the reality that the Word was made flesh is central to Catholicism. God has taken on human form. We can know Him. God is revealed to us in the sacred Humanity of Christ. Jesus should be our model and guide; we should seek to know Him through scripture, through prayer and through the Eucharist.

The Humanity of Christ was central to the spiritual life of many of the saints. St Teresa of Avila is particularly known for her devotion to the Humanity of Christ. It was while meditating in front of an image of Christ being scourged at the pillar that she experienced her deeper conversion to Christ.

Here are some words from St Teresa:

If Christ Jesus dwells in a man as his friend and noble leader, that man can endure all things, for Christ helps and strengthens us and never abandons us. He is a true friend. And I clearly see that if we expect to please him and receive an abundance of his graces, God desires that these graces must come to us from the hands of Christ, through his most sacred humanity, in which God takes delight.
Many, many times I have perceived this through experience. The Lord has told it to me. I have definitely seen that we must enter by this gate if we wish his Sovereign Majesty to reveal to us great and hidden mysteries. A person should desire no other path, even if he is at the summit of contemplation; on this road he walks safely. All blessings come to us through our Lord. He will teach us, for in beholding his life we find that he is the best example. 
What more do we desire from such a good friend at our side? Unlike our friends in the world, he will never abandon us when we are troubled or distressed. Blessed is the one who truly loves him and always keeps him near. Let us consider the glorious Saint Paul: it seems that no other name fell from his lips than that of Jesus, because the name of Jesus was fixed and embedded in his heart. Once I had come to understand this truth, I carefully considered the lives of some of the saints, the great contemplatives, and found that they took no other path: Francis, Anthony of Padua, Bernard, Catherine of Siena. A person must walk along this path in freedom, placing himself in God’s hands. If God should desire to raise us to the position of one who is an intimate and shares his secrets, we ought to accept this gladly.
