Pastor Dale is discussing a Wednesday night study on discipleship, focusing on foundational Christian principles. They have covered topics like salvation and baptism, and now they are exploring the body of Christ and the concept of the church. Pastor explains that before Christ's resurrection, the body of Christ did not exist. The church was a new concept introduced by Jesus, built on the foundation of His identity as the Christ, not on Peter himself. The word "church" (from the Greek "ekklesia") first appears when Jesus states that He will build His church, and this represents a new way for God to work on earth through a united body of believers.
Pastor Dale emphasizes the importance of believers assembling together, drawing from various scriptures to show that the church is how God witnesses to the world and builds up the body of Christ. They assert that the church is the last major work God is doing on earth, and Christians should remain in fellowship with the body. The church, despite its imperfections, is where God works, strengthens, and grows His people. Pastor concludes by urging Christians to stay in the church, as it is essential for discipleship and God's plan for the world.
