Jesus is to be Lord of the church. The church is to embody Jesus to the world. Do we reflect the love of God in Christ to one another and to the world? How else can the world know of Him?
“I believe that Jesus is the Christ, the Son of the Living God” was the expected confession of early Christians, and they were to make good on that confession in their lives.
