When [Jesus and the disciples] arrived back in Jerusalem, Jesus entered the Temple and began to drive out the people buying and selling animals for sacrifices. He knocked over the tables of the money changers and the chairs of those selling doves, and he stopped everyone from using the Temple as a marketplace. He said to them, "The Scriptures declare, 'My Temple will be called a house of prayer for all nations,' but you have turned it into a den of thieves."
— Mark 11:15-17 NLT
Jesus entered the Temple to restore it to its purpose. The Temple was to be a place of prayer. This place was to be open to all the nations. This place wasn't about making a profit off people seeking God. This place wasn't about merchandising the grace of God. While Jesus' actions were bold and shocking to those of his day, we have a tendency to let the distance in both time and culture soften the implications. When Jesus enters our hearts, our worship, and our religious places and times, what customs, ideas, and behavior will he drive away? Are we open to other nations and cultures? Are we about being a place and people of prayer? How have we sold out our Savior and our worship of him to our over-commercialized culture? How have we let religious charlatans fleece God-seeking people? And since our bodies are God's present-day temple (1 Corinthians 6:19-20), then what does this all mean for us?
