What does John 2:14 mean?
The presence of the livestock vendors and money changers in the temple probably started off with good intentions. Jewish people traveling long distances to the temple (Deuteronomy 16:16; John 2:13) did not always have the means to bring animals with them. It made sense to provide a way to purchase proper sacrifices. There would also be a need to help people convert their coins into local money. Apparently, turning a profit soon took over. More of a problem was that instead of conducting business near the temple, or just outside it, the marketplace had been moved inside the temple grounds.The area in question is known as the "Court of the Gentiles," just inside the borders of the temple. This should have been the place where Israel reached out to tell others about God. It was meant to be one of the spaces set aside for God's people to focus on God's purposes. Instead, it was being used as a blatant money grab (John 2:16).
Some interpreters see a warning here for modern ministries: to avoid allowing a ministry to lose sight of its original purpose. Worse is the threat of letting business concerns outweigh spiritual concerns, or a ministry becoming entirely profit-driven.
