When I was serving in my first pastorate, we had a lovely elderly couple in the church. Of course when I was that young, everybody was elderly. But they came to me one day and said, “Pastor we have moved into a new house and we’d like you to come and dedicate it.” That was an interesting experience. I had never done that before. I don’t think I’ve ever done it since. My wife and I went out to the house and we read Scripture, and we had prayer, and we dedicated that house to the glory of the Lord. What is the most important part of a house? Now think that through. Oh you say the foundation. Perhaps. The heating system, the plumbing, maybe. What is the most important part of a house? It’s the home that is in the house. You see many people have homes who don’t have houses. They might be renting or they might be traveling. The most important part of a house is the home in the house. Now what’s the most important part of the home? It’s the heart of the people who make up the home.
That’s what David had to say in Psalm 101. He was dedicating his house to the Lord. And he says in verse 2, “I will behave myself wisely in a perfect way. O when wilt Thou come unto me? I will walk within my house with a perfect heart.” Now in this Psalm he talks about two other kinds of hearts; a perverse heart in verse 4, a proud heart in verse 5. If you want to wreck your house, start wrecking your home. And if you want to wreck your home, start working on your heart. But if you want your house and your home to be all that it can be and all that God wants it to be, then make your heart a perfect heart. What is a perfect heart? Well, the word means “integrity,” “wholeness,” “oneness,” not a divided heart. Nobody can serve two masters. Nobody can plow and look back. You’ve got to have a heart that is integrated, a oneness of heart. “Unite my heart to fear Thy name” (Psalm 86:11) said David.
David walked around his new house and he said, I want my heart to be a perfect heart. I want my heart to be holy fixed upon the Lord. I want that He shall reign supremely in my home because He reigns supremely in my heart.
