If an employee of a company decides that they are not going to consider the good of the company when making decisions, the employee is not going to last long. In humanity’s natural state, this selfish attitude will invade all of life. How can the church be different? In this sermon on Ephesians 2:20–22 titled “Parts of the Whole,” Dr. Martyn Lloyd-Jones examines the startling reality of unity and diversity in the church because of the work of the Holy Spirit. The church is composed of many different stones and Dr. Lloyd-Jones asserts that it is the job of each stone to think of itself in relation to the rest of the building. He argues that many people are not grounded enough in their identity as a member of the church and tend to be too subjective. Also, many become selfish and claim aspects of the church (such as ministries, churches, and denominations) as their own, rather than focusing on serving for the glory of Christ. Each stone has a specific part to play in the wall, not with meaningless activity, but serving in whatever way God calls them to serve. Also, Dr. Lloyd-Jones notes that a dangerous mistake is when people start “doing without being.”
