My children, fill yourselves with wonder and gratitude at such a mystery and learn from it. All the power, all the majesty, all the beauty, all the infinite harmony of God, all his great and immeasurable riches, God whole and entire! was hidden for our benefit in the Humanity of Christ. The Almighty appears determined to eclipse his glory for a time, so as to make it easy for his creatures to approach their Redeemer.
'No man,' St John writes, 'has ever seen God; but now his only‑begotten Son, who abides in the bosom of the Father, has himself revealed him' , appearing to the astonished gaze of men: first, as a new-born babe, in Bethlehem; then, as a child just like other children; later on, in the Temple, as a bright and alert 12-year old; and finally in the lovable and attractive image of the Teacher who stirred the hearts of the enthusiastic crowds that accompanied him. (Friends of God, 111)
