Matthew 21:10-14 And when he was come into Jerusalem, all the city was moved, saying, Who is this? And the multitude said, This is Jesus the prophet of Nazareth of Galilee. And Jesus went into the temple of God, and cast out all them that sold and bought in the temple, and overthrew the tables of the moneychangers, and the seats of them that sold doves, And said unto them, It is written, My house shall be called the house of prayer; but ye have made it a den of thieves. And the blind and the lame came to him in the temple; and he healed them.
There is a long-standing tradition of cleaning one's house in the springtime – hence the term "spring cleaning". One source for this tradition is certainly the Jewish Passover (Pesach). Each spring as the holiday approaches observant householders in Israel and around the world perform a meticulous cleaning of their homes, especially to be sure there is no leaven in the house before Pesach begins. Leaven, in scripture, is often a metaphor for sin and impurity; and this season of the year is often a time for emphasizing "spiritual housecleaning".
When Yeshua (Jesus) entered Jerusalem for the last time in His earthly life, before the Passover, and just before He was sacrificed, He went to the Temple and "cleansed" it by driving out the money changers and religious merchandisers. Apparently, these were "religious" people with impure motives, and the Lord considered them to be "leaven" in his Father's house. Immediately after this, the Lord miraculously healed the blind and lame.
We can also be "religious" people with impure motives; seeking financial gain, or prestige, from "spiritual" activity, when the Lord desires a devoted heart of worship and prayer in His "house". Perhaps this is why we see so few miracles in our lives and "ministries". Let us also do a "housecleaning" for impure motivations. The Lord may then be freer to work His miracles through us.
