““The church is called a mystery that was not revealed to past generations, but was revealed for the first time in the New Testament era. This mystery involved the idea of uniting Jewish and Gentile believers in one spiritual body (see Ephesians 3:3-6,9; Colossians 1:26-27). This lends support to the idea that the church age began on the day of Pentecost. (Individual Jews may become members of the church by faith in Christ in the present age, but God still has a future purpose for Israel. This will become increasingly clear throughout this book.)””
