33 You sent to John, and he has borne witness to the truth. 34 Not that the testimony which I receive is from man; but I say this that you may be saved. 35 He was a burning and shining lamp, and you were willing to rejoice for a while in his light. 36 But the testimony which I have is greater than that of John; for the works which the Father has granted me to accomplish, these very works which I am doing, bear me witness that the Father has sent me.
Jesus is asking each and every one of us to identify the works of God in this world. John Baptist was the light which identified the presence of Christ in this world. We as a baptised Christians are equally called to witness this light in this world.
This light is however accessible to all, because the divine works do give the best witness of this light. Since God resides in us, we are invited to give visibility to this divine work through our words and deeds.
It is in this vocation and accomplishing this mission that we will find the eternal joy. Through our life giving witness that others identify the presence of God and see themselves the divine work. Christmas gives us one such occasion.
Daily Quote from the early church fathers:
The prophets and apostles are lamps of God, by Augustine of Hippo, 354-430 A.D.
"All people are lamps because they can both be lighted and extinguished... Only [Christ] is not a lamp. For he is not lighted and extinguished, because "as the Father has life in himself, so he has given to the Son to have life in himself." Therefore, the apostles, too, are lamps. And they give thanks because they both have been kindled by the light of truth and burn with the Spirit of love, and the oil of God’s grace is available to them. If they were not lamps, the Lord would not say to them, "You are the light of the world" (Matthew 5:14). For after he said, "You are the light of the world," he shows that they should not think they were such a light as that of which it is said, "It was the true light that enlightens everyone who comes into this world." (excerpt from TRACTATES ON THE GOSPEL OF JOHN 23.3.1–2).
