To relate to God, you must do it “covenantally.” He wants all of you; he wants every aspect of you; he wants every bit of you.” It’s silly, but it’s natural that American Christians will say to me, “I have a personal relationship with Jesus Christ. Why do I have to join a church?” I say, “What do you mean?”
“Where does it say in the Bible that I have to join a church?”
“On every page,” if you understand the covenant. All joining a church means is you’re willing to make a public vow that makes you accountable for your whole life. That’s what we don’t like because, “Who needs that? The most important thing is the personal and the spontaneous.”
No! The most important thing is every part of you has to go to him. You’re supposed to make yourself a whole burnt offering on the altar. That’s what it says in Romans 12 where it says, “Make yourself a living sacrifice, a whole burnt offering, to the Lord.”
