House
A "house" is essentially a container -- for a person, a family, several families or even a large group with shared interests (think of the term "houses of worship.") In the Bible, a "house" is also a container, but for spiritual things rather than natural things. In various uses a "house" can represent part of the mind, the whole mind, a whole person or even a church. The other nuance to the word "house" is that it is generally used in regards to our affections and desires rather than our thoughts and principles. This makes sense; we tend to engage our thoughts and rationality when we are out in the world doing our work, but when we are inside our houses we are driven most by love for our families and the desire to be good to those we love. So "house" tends to represent the things we want and care about -- which are ultimately the things that define us.
John 4:35-38
35
Don't you say, 'There are yet four months until the harvest?' Behold, I tell you, lift up your eyes, and look at the fields, that they are white for harvest already.
36
He who reaps receives wages, and gathers fruit to eternal life; that both he who sows and he who reaps may rejoice together.
37
For in this the saying is true, 'One sows, and another reaps.'
38
I sent you to reap that for which you haven't labored. Others have labored, and you have entered into their labor."
