In the first instance, this was an encounter not with concepts or ideas but with the person of Jesus himself. In fact, Paul met not only the historical Jesus of the past, but the living Christ who revealed himself as the one Saviour and Lord. Similarly, the ultimate source of our own conversion lies neither in esoteric philosophical theories nor abstract moral codes, but in Christ and his Gospel.
He alone defines our identity as Christians, since in him we discover the ultimate meaning of our lives. Paul, because Christ had made him his own (cf. Phil 3:12), could not help but preach the Good News he had received (cf. 1 Cor 9:16). So it is with us. Transfixed by the greatness of our Saviour, we – like Saint Paul – cannot help but speak of him to others. May we always do so with joyful conviction!
