“You will see greater things than these” (Jn 1:50), Jesus said to Nathanael. To become one who sees is, then, the meaning of coming to Jesus. Coming to Jesus means entering into the state of being seen by him and sharing his ability to see. Above where he dwells, the heavens open, the hidden realm of God (Jn 1:51). There we stand in God’s holiness.
“Come and you will see”- the words are reminiscent of the Communion Psalm of the Church: “O taste and see the goodness of the Lord” (Ps 33:8). It is coming, then, and only coming, that leads to seeing. Tasting opens the eyes. Just as once in paradise the eyes of Adam and Eve were so fatefully opened by their eating of the forbidden fruit, so the opposite is true here – the tasting of truth opens the eyes so that we see how good God is. Only in coming, only in Jesus’ abode, are we able to see.
Without the risk of coming, there can be no seeing. John comments: “It was the tenth hour” (1:39), that is, it was a very late hour in which one does not expect to accomplish anything more, yet in it something crucial and decisive is taking place. According to some apocalyptic theories, this was thought to be the hour of the end of time. Whoever comes to Jesus enters into what is final, into the end of time; he encounters the parousia, the ever-present reality of the Ressurection and the Kingdom of God. It is in coming, then, that we see…Certainly we have all begun our journey with the Church’s full acknowledgment of the Son of God, but this kind of coming “at your word”, this kind of going to his abode is, nevertheless, for us too a prerequisite of our own seeing. And it is only those who are themselves able to see, who are no longer secondhand believers, who can make disciples of others. This coming, this venturing on his word, is today and always the unalterable precondition for such an apostolate.
