To all that be in Rome, beloved of God, called to be saints: Grace to you and peace from God our Father, and the Lord Jesus Christ. First, I thank my God through Jesus Christ for you all, that your faith is spoken of throughout the whole world. Romans 1:7-8
So, as much as in me is, I am ready to preach the gospel to you that are at Rome also. Romans 1:15
Many Christians mistakenly believe that the gospel is just for the lost – once a person is saved, they move on from the gospel and learn Christian doctrines and practices. But notice what Paul said when he wrote to those in Rome. In verses 7 & 8, we see Paul is writing to believers – to those who already have faith. Then in verse 15, Paul says he is ready to preach the gospel to them. If the gospel is for unbelievers, why would Paul want to preach the gospel to them? Does he think they are false professors – pretending to be Christians? No, he says their faith is spoken of throughout the whole world. So why would Paul preach the gospel to believers? The answer is simple:
For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. Romans 1:16
The gospel is the power of God. It is the power of God to save. It is the power of God to transform a life. It is the power of God to conform us to the image of his son.
The entire Bible is about the person and work of Christ. The gospel is about the person and work of Christ. A sermon taken from scripture that only presents the do’s and don’ts without showing the relationship to the person and work of Christ is not a Christian sermon. It may be given by a Christian and directed towards Christians, but if it is not preaching the gospel as the power of God, it is not a Christ-centered sermon. The life a Christian should live is grounded and nourished by the person and work of Christ. Don’t just tack on a simple gospel presentation at the end of the message. The whole message should be the gospel.
