Psalm 27:4 (NKJV)
One thing I have desired of the Lord, That will I seek: That I may dwell in the house of the Lord All the days of my life, To behold the beauty of the Lord, And to inquire in His temple.
It is this kind of single minded desire that David had which confirms to us his whole heart for God. He paints a wonderful picture of being in the presence of God, which involves prayer (inquire in His temple) and praise (beholding the beauty of the Lord). David calls this a desire to "dwell in the house of the Lord all my days." So what is the house of the Lord? In David's day, it was equated with the portable tabernacle in which the ark of the covenant was placed. That is where God had promised to live so as to be among his people.
What about today since we have no temple or ark? Surely we wouldn't consider just hanging out at Church to be "dwelling in the house of the Lord." It must mean more than that. How can we dwell the presence of the Lord? It still involves prayer and praise but there is a new house God dwells in. God no longer has a temporary residence, he has moved into a permanent home, the heart of the believer!
1 Corinthians 3:16 (NKJV)
Do you not know that you are the temple of God and that the Spirit of God dwells in you?
I heard my pastor say just yesterday, "Real salvation is not getting man out of earth into heaven, but rather getting God out of heaven into man."
