Today's Second Reading tells us that had God's grace not been given to us through St. Paul, we as Gentiles, would not qualify to be fellow heirs as members of the Body of Christ and sharers in the promise of Jesus through the Gospel. For until the moment when it was revealed to St. Paul, the Gentiles had been set apart from God's people. The promises of God that were made to the prophets of the Old Testament excluded all the nations except the Jewish people, God's chosen people. Therefore, as the great prophet Isaiah rejoiced with the people when they reached Jerusalem, the City of God, we also rejoice because through the Sacrament of Baptism, we entered the Body of Christ as spiritual members of the Kingdom of God. The reading of today's Gospel is one of the best told stories among Christians.
Children love to hear it over and over.
When they finally found Jesus, they were overwhelmed with joy. Being blessed by God with this great honour of being before Jesus, they looked down at this little Child and knew in their minds that one day, He would redeem the world as the King of kings. While the three wise men may have had a thousand questions on their mind to ask Jesus as to how this would be achieved, they could not ask one. Because Jesus was still a little Child. So all they could do was stare at Jesus, prostrate before Him, adore Him, be overwhelmed with joy at the great knowledge that they had regarding the Child Jesus.
