Romans 10:14–15
"And how shall they hear without a preacher? And how shall
they preach unless they are sent? As it is written: 'How beautiful
are the feet of those who preach the gospel of peace, who bring glad
tidings of good things!' "
From the original Greek, we could translate the final question in
Romans 10:14 as, "How shall they hear without one preaching?"
The Phillips translation puts it this way, "How can they hear
unless someone proclaims Him?" Therefore, we see the emphasis
is not on a preacher, but on preaching.
We may think the work of evangelism is only for those who are called to be evangelists. Granted, there are people in the church whom God has raised up to be evangelists, and certainly evangelism is not limited to those who preach to hundreds or thousands at a time. I have seen many individual believers who obviously have this gift.
While it is true that some are called to be evangelists, it is also true that every Christian is called to evangelize. Many times, however, we avoid sharing our faith, deciding instead to just live it out, be a good witness, and leave the preaching to others.
Yet in 1 Corinthians 1:21, it says, "For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message preached to save those who believe."
This does not mean that we need to scream and yell and wave a Bible to get the point across. What it does mean is that we are to recognize the primary way God has chosen to reach the lost is through the proclamation of the gospel–by people. God has chosen the agency of His proclaimed Word to bring people to salvation.
Matthew 28:19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
Acts 1:2 until the day he was taken up to heaven, after giving instructions through the Holy Spirit to the apostles he had chosen.
Acts 1:8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."
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.
