Whenever these verses of the Bible are read, my mind harkens back to when I was young, back in the Philippines. There the approaches to the churches were full of vendors selling their wares.
And so if our body is the temple of the Holy Spirit, it should be a temple devoted solely to prayer.
I propose that when Jesus drove all those vendors out of the temple, he was also telling us to get rid of our own marketplace attitude towards God. He was telling us to remove all evil desires, like greed, envy, malice and pride from our bodies, and from of our lives. They are the thieves that steal our peace. Instead we should use our bodies as they were designed to be used: for prayer.
In CCC 2559, we read: “'Prayer is the raising of one’s mind and heart to God or the requesting of good things from God' But when we pray, do we speak from the height of our pride and will, or 'out of the depths' of a humble and contrite heart?...'Man is a beggar before God.' Not a buyer or seller. We are not in a position to haggle with God.
In CCC 2562: “Where does prayer come from? Whether prayer is expressed in words or gestures, it is the whole man who prays.... According to Scripture, it is the heart that prays. If our heart is far from God, the words of prayer are in vain.”
If in the depths of our heart, if in the house of the living God, if in the temple of the Holy Spirit, there is humble prayer, it truly becomes God's abode.
