17. True, no one has ever seen God as he is. And yet God is not totally invisible to us; he does not remain completely inaccessible. God loved us first, says the Letter of John quoted above (cf. 4:10), and this love of God has appeared in our midst. He has become visible in as much as he “has sent his only Son into the world, so that we might live through him” (1 Jn 4:9). God has made himself visible: in Jesus we are able to see the Father (cf. Jn 14:9). Indeed, God is visible in a number of ways. In the love-story recounted by the Bible, he comes towards us, he seeks to win our hearts, all the way to the Last Supper, to the piercing of his heart on the Cross, to his appearances after the Resurrection and to the great deeds by which, through the activity of the Apostles, he guided the nascent Church along its path. Nor has the Lord been absent from subsequent Church history: he encounters us ever anew, in the men and women who reflect his presence, in his word, in the sacraments, and especially in the Eucharist. In the Church's Liturgy, in her prayer, in the living community of believers, we experience the love of God, we perceive his presence and we thus learn to recognize that presence in our daily lives. He has loved us first and he continues to do so; we too, then, can respond with love. God does not demand of us a feeling which we ourselves are incapable of producing. He loves us, he makes us see and experience his love, and since he has “loved us first”, love can also blossom as a response within us.
In the gradual unfolding of this encounter, it is clearly revealed that love is not merely a sentiment. Sentiments come and go. A sentiment can be a marvellous first spark, but it is not the fullness of love. Earlier we spoke of the process of purification and maturation by which eros comes fully into its own, becomes love in the full meaning of the word. It is characteristic of mature love that it calls into play all man's potentialities; it engages the whole man, so to speak. Contact with the visible manifestations of God's love can awaken within us a feeling of joy born of the experience of being loved. But this encounter also engages our will and our intellect. Acknowledgment of the living God is one path towards love, and the “yes” of our will to his will unites our intellect, will and sentiments in the all- embracing act of love. But this process is always open-ended; love is never “finished” and complete; throughout life, it changes and matures, and thus remains faithful to itself. Idem velle atque idem nolle —to want the same thing, and to reject the same thing—was recognized by antiquity as the authentic content of love: the one becomes similar to the other, and this leads to a community of will and thought. The love-story between God and man consists in the very fact that this communion of will increases in a communion of thought and sentiment, and thus our will and God's will increasingly coincide: God's will is no longer for me an alien will, something imposed on me from without by the commandments, but it is now my own will, based on the realization that God is in fact more deeply present to me than I am to myself. Then self- abandonment to God increases and God becomes our joy (cf. Ps 73 :23-28).
18. Love of neighbour is thus shown to be possible in the way proclaimed by the Bible, by Jesus. It consists in the very fact that, in God and with God, I love even the person whom I do not like or even know. This can only take place on the basis of an intimate encounter with God, an encounter which has become a communion of will, even affecting my feelings. Then I learn to look on this other person not simply with my eyes and my feelings, but from the perspective of Jesus Christ. His friend is my friend. Going beyond exterior appearances, I perceive in others an interior desire for a sign of love, of concern. This I can offer them not only through the organizations intended for such purposes, accepting it perhaps as a political necessity. Seeing with the eyes of Christ, I can give to others much more than their outward necessities; I can give them the look of love which they crave. Here we see the necessary interplay between love of God and love of neighbour which the First Letter of John speaks of with such insistence. If I have no contact whatsoever with God in my life, then I cannot see in the other anything more than the other, and I am incapable of seeing in him the image of God. But if in my life I fail completely to heed others, solely out of a desire to be “devout” and to perform my “religious duties”, then my relationship with God will also grow arid. It becomes merely “proper”, but loveless. Only my readiness to encounter my neighbour and to show him love makes me sensitive to God as well. Only if I serve my neighbour can my eyes be opened to what God does for me and how much he loves me. The saints—consider the example of Blessed Teresa of Calcutta—constantly renewed their capacity for love of neighbour from their encounter with the Eucharistic Lord, and conversely this encounter acquired its real- ism and depth in their service to others. Love of God and love of neighbour are thus inseparable, they form a single commandment. But both live from the love of God who has loved us first. No longer is it a question, then, of a “commandment” imposed from without and calling for the impossible, but rather of a freely-bestowed experience of love from within, a love which by its very nature must then be shared with others. Love grows through love. Love is “divine” because it comes from God and unites us to God; through this unifying process it makes us a “we” which transcends our divisions and makes us one, until in the end God is “all in all” (1 Cor 15:28).
