"Is it not written: "My house will be called a 'house of prayer for all nations?'" But you have made it 'a den of robbers'"
“‘Will you steal and murder, commit adultery and perjury, burn incense to Baal and follow other gods you have not known, and then come and stand before me in this house, which bears my Name, and say, “We are safe”—safe to do all these detestable things? Has this house, which bears my Name, become a den of robbers to you? But I have been watching!' declares the LORD."
"And foreigners who bind themselves to the LORD to minister to him,
to love the name of the LORD,
and to be his servants,
all who keep the Sabbath without desecrating it
and who hold fast to my covenant—
these I will bring to my holy mountain
and give them joy in my house of prayer.
Their burnt offerings and sacrifices
will be accepted on my altar;
for my house will be called
a house of prayer for all nations.”
Jesus makes it clear the stark contrast between a true believer and a pretender, those who truly love God and go to church and those who go to church so that they will be loved by God, between true and false religion. We, who bear the name of Christ, are his house. Have you been washed or are you impure?
