“This is what the LORD Almighty says: ‘Ask the priests what the law says: If someone carries consecrated meat in the fold of their garment, and that fold touches some bread or stew, some wine, olive oil or other food, does it become consecrated?’ ”
The priests answered, “No.”
Then Haggai said, “If a person defiled by contact with a dead body touches one of these things, does it become defiled?”
“Yes,” the priests replied, “it becomes defiled.”
Then Haggai said, “So it is with this people and this nation in my sight,’ declares the LORD. ‘Whatever they do and whatever they offer there is defiled.” Haggai 2:11-14 (NIV)

Okay, this seems like some strange verses for us to apply to our time. In this passage, the exiled people of Judah have returned to Jerusalem and have attempted to rebuild the Temple which had been destroyed. However, the people are disappointed by what they have achieved.

As I understand what the prophet Haggai is saying to his people is basically: “If the people haven’t consecrated themselves to God, how can they expect to build a Temple befitting the glory of God.”
How does that apply to us?
If we as a people of God do not clean up our own act, how can we expect the rest of the world to do so? Can we really expect revival? Can we expect the world to turn to our God?
If our actions and our messages to the world are filled with hate, infidelity, corruption, greed, and the like, we are building an awful example of a Temple. It is true that we are imperfect and none of us is without sin. However, the Bible tells us that everyone will know us if we love one another (John 13:35). Love covers a multitude of sins (1Peter 4:8).
Not saying we should tolerate sin, but the first place to weed it out is in ourselves.
