Jesus came “to seek and to save that which was lost” (Luke 19:10). He then leaves the sought and saved in the world to continue that work. Christians are not all evangelists vocationally, but we are all evangelists in the 1 Peter 3:15 sense. A desire for the salvation of others is both a mark and the duty of every believer.
Christians are those who believe the gospel. Whether it is by a parent in the home, a minister in the church, or a friend in private conversation, we must be evangelized to be saved by Jesus Christ.
Furthermore, according to the four Gospels of the New Testament, the Christian faith is designed to be shared with others. The evangel is evangelistic! A true Christian church is not only evangelical, in that it holds to the Biblical gospel, but it is evangelistic—it zealously spreads and shares that gospel. This means that to be a Christian is to be called as an evangelist.
. . .
All Christians are called to evangelism. Jesus the Evangelist is our model. If we want to experience the power of God in our gospel witness, we must follow biblical principles of evangelism; we must present the true gospel in clear, scriptural terms; and we must follow Jesus’ example in the practice of evangelizing actual people. Let us seek God’s blessing for the salvation of many by preparing ourselves to be faithful witnesses to the gospel of God’s grace.
