I keep going back to this paragraph of pope Francis in the last General Audience of 2015:
We discover, first of all, that children want our attention. They have to be at the centre — why? Because they are proud? No! Because they need to feel protected. It is important that we too place Jesus at the centre of our life and to know, even if it may seem paradoxical, that it is our responsibility to protect him. He wants to be in our embrace, he wants to be tended to and to be able to fix his gaze on ours. Additionally, make the Child Jesus smile in order to show him our love and our joy that he is in our midst. His smile is a sign of the love that gives us the assurance of being loved. Children, lastly, love to play. Playing with children, however, means abandoning our logic in order to enter theirs. If we want to have fun it is necessary to understand what they like, and not to be selfish and make them do the things that we like. It is a lesson for us. Before Jesus we are called to abandon our pretense of autonomy — and this is the crux of the matter: our pretense of autonomy — in order to instead accept the true form of liberty, which consists in knowing and serving whom we have before us. He, the Child, is the Son of God who comes to save us. He has come among us to show us the face of the Father abounding in love and mercy. Therefore, let us hold the Child Jesus tightly in our arms; let us place ourselves at his service. He is the font of love and serenity. It will be beautiful today, when we get home, to go to the nativity scene and kiss the Baby Jesus and say: “Jesus, I want to be humble like you, humble like God”, and to ask him for this grace.
