This is the great news that Jesus announced to humanity: that we have the possibility of becoming children of God through grace.
But how and to whom is this grace given? “To those who did accept him” and to those who will accept him in the course of centuries. We must accept Jesus in faith and in love, believing in him as our Savior.
But let’s try to understand more deeply what it means to be children of God.
It is enough to look at Jesus, the Son of God, and at his rapport with the Father: Jesus prayed to his Father as in the “Our Father.” For him the Father was “Abba”; which means Dad, a Person he turned to with infinite trust and limitless love.

However, since he came on earth for us, it was not enough for him to be the only one in this privileged position. By dying for us, redeeming us, he made us children of God, his own brothers and sisters. And through the Holy Spirit he also gave us the possibility of being introduced into the bosom of the Trinity, so that we too have the possibility of repeating the same divine invocation: “Abba, Father!” (Mk. 14:36; Rm. 8:15). “Dad, my!, our Dad.” This invocation implies the certainty of his protection, confidence, trustful surrender to his love, divine consolation, strength, ardor, the ardor you experience when you are certain of being loved.

«But to those who did accept him he gave power to become children of God.»

What makes us one with Christ and, with him, sons and daughters in the Son, is baptism and the life of grace that comes from it.
Moreover, this passage from the Gospel also reveals to us the profound dynamism of being children of God, which we need to live out day after day. In fact, it is necessary “to become children of God.”
We become, we grow as children of God, by corresponding to his gift, by living his will which is all summed up in the commandment of love: love towards God and love towards neighbors.
To accept Jesus means to recognize him in all our neighbors. And they too will have the possibility of recognizing Jesus and of believing in him if they are able to discern in our love for them, a glimmering, a spark of the boundless love of the Father.

«But to those who did accept him he gave power to become children of God.»

During this month in which we celebrate Jesus’ birth on earth, let’s try to accept one another by seeing and serving him in one another.
A reciprocity of love, knowledge, and life like that which links the Son to the Father in the Spirit, will be established also between us and the Father, and Jesus’ invocation: “Abba, Father,” will ever be on our lips.
