House of the LORD

I think the House of the Lord accuratly describes the Church.

2Sa 7:4 And it came to pass that night, that the word of the LORD came unto Nathan, saying,
2Sa 7:5 Go and tell my servant David, Thus saith the LORD, Shalt thou build me an house for me to dwell in?
2Sa 7:6 Whereas I have not dwelt in any house since the time that I brought up the children of Israel out of Egypt, even to this day, but have walked in a tent and in a tabernacle.

We know that is not true today.

Mat 18:2 For where two or three are gathered together in my name, there am I in the midst of them.

2Sa 7:12 And when thy days be fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom.

Jesus the son of David

2Sa 7:13 He shall build an house for my name, and I will stablish the throne of his kingdom for ever.

The Church

2Sa 7:14 I will be his father, and he shall be my son. If he commit iniquity, I will chasten him with the rod of men, and with the stripes of the children of men:

The LORD will be the father of the Church

2Sa 7:15 But my mercy shall not depart away from him, as I took it from Saul, whom I put away before thee.

Infinite Grace

2Sa 7:16 And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever.

Eternal security

2Sa 7:17 According to all these words, and according to all this vision, so did Nathan speak unto David.

2Sa 7:18 Then went king David in, and sat before the LORD, and he said, Who am I, O Lord GOD? and what is my house, that thou hast brought me hitherto?

David did not understand what this house would be.
