Most Christians feel unworthy to share Christ with others. Even if a believer is especially godly he or she should never feel adequate or qualified to share the gospel. Fortunately, the good news of the gospel is a free gift (Eph 2:8-9) and is not dependent upon our performance (Titus 3:5). Consequently, any believer can and should share the gospel with family, friends, neighbors, coworkers, and acquaintances. God commands every Christian to share the gospel (Matt 28:19-20; Mark 16:15; Luke 24:47-49; Acts 1:8). These passages are relevant not only to the first-century apostles but also to all 21st century disciples.

A wonderful example of a faithful witness is the immoral woman in John 4:7-30. After Jesus shared eternal life with her, she "left her waterpot, and went into the city and said to the men, 'Come, see a man who told me all the things that I have done; this is not the Christ, is it?'" (4:28-29). Later in the chapter, John records, "From that city many of the Samaritans believed in Him because of the word of the woman who testified, 'He told me all the things that I have done'" (4:39). This woman is a wonderful example of an unworthy candidate to share the gospel that was powerfully used by Christ.

Although the Holy Spirit can work in and through us in spite of ourselves, it is imperative that we exhort Christians to be "salt and light" (Matt 5:13-16) and "walk in a worthy manner" (Eph 4:1). Generally, those Christians who act most like Christ are the most effective ambassadors of the gospel (2 Cor 5:20).
