In the book of Revelation, we read about the marriage of the Lamb (Revelation 19:7). The Bible has been described as a divine romance. God loves us and pursues a personal relationship with us. Believers receive the love of God in Christ (John 3:16).
The Lamb is none other than our Lord Jesus Christ. John the Baptist introduced Jesus as "the Lamb of God who takes away the sin of the world" (John 1:29). He is every believer's Passover Lamb at the cross (1 Corinthians 5:7). God proved his love for sinners at the cross of Jesus (Romans 5:8).
The New Testament teaches that the church is the bride of Christ. The church is not a denomination nor a sectarian group. The church includes all who have been saved by grace through faith in Christ. The church is a mystery not revealed in the Old Testament. The church is revealed in the New Testament (Ephesians 3:1-6). All believers compose the body of Christ. He is the head of the body (Ephesians 5:23).
Wedding customs in New Testament days illustrated the relationship with Christ and the church. The father chose the bride for his son. God the Father chose the church as the bride for His Son. Believers are the bride-elect of Christ. Marriage was a covenant relationship. Christ is the Shepherd of the everlasting covenant (Hebrews 13:20-21). A dowry price was paid for a bride. Jesus paid it all for his bride at the cross (Ephesians 5:25).
