“Paul, a servant of Christ Jesus, called to be an apostle, set apart for the gospel of God,” (Romans 1:1 ESV)
A slave. Paul viewed himself as a slave (Greek word for servant is also translated “slave”) of Jesus. He was under the authority, rule and command of Jesus. This thinking is used throughout Paul’s writings. We are a slave to sin or to righteousness; to the flesh or the Spirit. Slaves are purchased, they have an owner and master. For the Christian that owner is God, the purchase price was the blood of the Son of God. We have been legally transferred from one kingdom to another; we have been delivered from darkness to light; moreover, we have been adopted into God’s family. We have been emancipated from the bondage to sin. We are first, and foremost purchased by Christ before we are ever called to go and do anything.
The Gospel of God is the proclamation of good news regarding God’s redemptive purposes in the world which are culminated in the life, death, burial and resurrection of Jesus. The gospel is not only a call to saving faith, but the comprehensive message about Jesus’ redemption of all things – this gospel saves us AND transforms us. It is comprehensive from start to finish as the letter of Romans boldly proclaims. The gospel reconciles and sanctifies.
“The noun euangelion [translated gospel] originally signified announcement of victory after battle and later the content of that message. The term also came to describe the birth or the rise to power of a new king. An inscription from Priene in Asia Minor, probably written around 9 B.C. describes the enthronement of Augustus as the new Roman emperor. Augustus is lauded as the savior who will bring peace and hails his birthday as “the beginning of the glad tidings (euangelion) that have come to men through him.” This illustrates the religious content of the term in emperor worship.
When one compares pagan use of euangelion and the LXX’s [Greek translation of the Old Testament] use of euangelizomai, a striking parallel arises of a king worshiped by his people. The gospel and its confession that Jesus is Lord confront the claim that Caesar is Lord and declare that in the cross and resurrection Jesus is enthroned as the King of kings. Caesar or any other created thing claiming lordship will bow before the crucified and risen Jesus. “GOSPEL,” Holman Illustrated Bible Dictionary, n.p.
