In today's Gospel we have Mary going to Zechariah's house and visiting her cousin Elizabeth. We have a sequence of events worth considering; Mary greets Elizabeth (speaks), Elizabeth hears the greeting (listens), Elizabeth's child, John the Baptist, leapt in her womb and then Elizabeth is filled with the Holy Spirit.
This type of sequence appears in other parts of the Bible; take Mark 16:15 where Jesus tells the disciples 'Go out to the whole world; proclaim the gospel to all creation.'
During our day-to-day encounters we hear many people speak. It is up to us to listen to what is being said and then contemplate within ourselves the source (is God telling us something more than just the words say?). Will we rejoice as Elizabeth did and allow the Holy Spirit, through us, to proclaim God's love in our lives to others?
