God created man with a need to belong. We were not designed to exist in isolation but in community with God and each other. At creation, God said, “It is not good that the man should be alone” (Genesis 2:18). We need a relationship with God to be fulfilled, but we also need relationships with other people where we enjoy mutual love and acceptance.
Adam’s need for belonging was met perfectly by God and Eve before the fall, but sin corrupted mankind’s relationship to God and each other. Through faith in Christ, we are restored to a right relationship with God so that when we are saved, we are restored to the right communion with God. We belong to Him.
But the gospel does not only restore our relationship with God. Christians belong to a unique group of people who belong to Jesus. This is why the Bible uses such language as is found in Acts two. “Then they that gladly received his word were baptized: and the same day there were added unto them about three thousand souls. And the Lord added to the church daily such as should be saved.” (Acts 2:41, 47) They had a place where they belonged in the body of Christ. And God continued to add to the church so that more and more people found a place where they belonged.
Each of us needs to belong. God wants to meet that need first through salvation so that you belong to Him and then through the church, a community of people that belong to Christ. The church belongs to Christ, and if you belong to Christ, then church is where you belong.
