What was Jesus so angry about?
When I get to the movie theater, I have to buy a ticket and cannot bring in any outside food or drink. If I can't afford it, I don't see a movie and I go hungry & thirsty. When I come to Christian worship, I don't have to pay anything and they serve me the Lord's Supper for free (probably coffee hour goodies too!)
I don't think Jesus is angry about people doing business in church, or even turning a profit. It isn't about the money. It is about worship. They were holding worship hostage for those who could afford to pay. This is the reason he is especially angry at the sellers of doves--those were the animal sacrifices that very poor people offered.
For interesting comparisons, read Mark 12:41-44 and Matt 17:24-27.
What barriers are in your worship space that would keep newcomers away? Prayer: Lord God, help me to offer my whole self to you in worship: my attention, my mind, my praise, my talents and my money. Amen.
