"Whoever loves me will be loved by my Father, and I will love him and reveal myself to him." (Jn 14:21)

Love is the focus of Jesus’ farewell discourse: the love of the Father for the Son, the love for Jesus which means keeping his commandments.

Those who were listening to Jesus could easily recognize in his words an echo of the Book of Wisdom: "Loving her means keeping her laws" (Wis 6:18) and, "She is readily perceived by those who love her" (Wis 6:12). In particular, Christ’s revealing himself to those who love finds a parallel in the Hebrew Scriptures - in Wisdom 1:2 where it says that the Lord will manifest himself to those who believe in him.

In other words, the Father loves those who love the Son, and the Son in turn loves them and reveals himself to them.

"Whoever loves me will be loved by my Father, and I will love him and reveal myself to him."

Jesus, however, demands that one loves. We cannot conceive of Christians who do not have this dynamism, this charge of love in their hearts. A clock doesn't work, it doesn't tell us the time – we wouldn't even call it a clock – if its batteries are dead. It's the same with Christians. If they are not constantly striving to love, they are not worthy of the name Christian.

The reason for this is that all of Christ’s commandments can be summed up in one: love of God and love of neighbor, in whom we recognize and love Jesus.

Love is not just a matter of feelings; it needs to be expressed in concrete terms, in serving our brothers and sisters, especially those who are near us and beginning with the small things, the most humble acts of service.

Charles de Foucauld once said: “When you love someone, you are really in that person through love, you live in him through love, you no longer live in yourself, you are detached from yourself, outside of yourself.”

When we love, the light of Jesus makes its way into our hearts, just as he promised: "I will reveal myself... to the one who loves me" (see Jn 14:21). Love is the source of light. By loving we have a greater understanding of God who is Love.

This leads us to love even more and to deepen the relationship with our neighbor.

This light, this loving knowledge of God, is therefore the seal, the proof of true love. We can experience it in different ways, because light takes on a particular color or shade in each one of us. But it also has common characteristics: it helps us to understand the will of God, it gives us peace, serenity, and an ever new understanding of the word of God. It's a heart-warming light which encourages us to walk along the way of life with growing confidence and determination. When the shadows of life make our way uncertain, when darkness threatens to stop us, these words of the Gospel will remind us that light is turned on by loving and that even one small gesture of concrete love (a prayer, a smile, a word) will give us enough light to go forward.

Some bicycles have a headlight that works as long as you keep peddling them. If you stop, you find yourself in darkness, but if you start peddling again, your action will provide the light you need to see the way ahead.

We can apply this to our life: we need only to re-activate love, true love, that love which gives to others without expecting anything in return, in order to re-enkindle within ourselves faith and hope.
