Jesus came to preach about the gospel of God (Mk.1:14 NET), and in turn, we are to preach the Gospel, the good news about who Jesus is, what He has done, and how we receive His benefits. Jesus sought out sinners by going into their midst, so likewise, we are to go out to seek lost souls. Therefore, be an ambassador (apostolos) of Christ (2 Cor. 5:20) just as Christ is an apostle (apostolos) for God.
