46 At first glance, all this may smack of pious sentimentalism. Yet it is supremely serious and of decisive importance, and finds its most sublime expression in Christ crucified. The cross is Jesus’ most eloquent word of love. A word that is not shallow, sentimental or merely edifying. It is love, sheer love. That is why Saint Paul, struggling to find the right words to describe his relationship with Christ, could speak of “the Son of God, who loved me and gave himself for me” ( Gal 2:20). This was Paul’s deepest conviction: the knowledge that he was loved. Christ’s self-offering on the cross became the driving force in Paul’s life, yet it only made sense to him because he knew that something even greater lay behind it: the fact that “he loved me”. At a time when many were seeking salvation, prosperity or security elsewhere, Paul, moved by the Spirit, was able to see farther and to marvel at the greatest and most essential thing of all: “Christ loved me”.
