All Christians are evangelists. Jesus tells us this in Mark 16:15: “Go into all the world and preach the good news to all creation.” As a Christian with a job, your place of employment is part of “all the world…all creation.”
Your message is one of good news and glad tidings.
Jesus is both the evangelist and the Good News. Luke 4:18–19 records the story of Jesus’s return to his hometown of Nazareth where he announced the purpose of his ministry this way:
“The Spirit of the Lord is on me, because he has anointed me to preach good news to the poor. He has sent me to proclaim freedom for the prisoners and recovery of sight for the blind, to release the oppressed, to proclaim the year of the Lord’s favor.” (emphasis added)
Note the words Jesus uses to describe his ministry: “good news…freedom…recovery…release…favor.”
Jesus evangelized his former neighbors with good news, not with condemnation, scare tactics, or doom.
To “preach good news” is translated from the Greek word euaggelizo, which is the root of the English word, “evangelize.” To evangelize is to announce the Messiah. The NKJV translates the same word in Luke 8:1 as “bringing the glad tidings.”
Your ministry in the workplace is not to condemn your coworkers but to bring the good news and glad tidings of Jesus Christ.
The ministry of reconciliation
Second Corinthians 5:18–20 describes your ministry this way:
All this is from God, who reconciled us to himself through Christ and gave us the ministry of reconciliation: that God was reconciling the world to himself in Christ, not counting men’s sins against them. And he has committed to us the message of reconciliation. We are therefore Christ’s ambassadors, as though God were making his appeal through us. (emphasis added)
God gave us the ministry of reconciliation with a message of reconciliation, and he is making his appeal to others through us.
You have already heard the good news, been reconciled to Christ, and are experiencing his blessings. As one of Christ’s ambassadors (2 Cor 5:20) to the workplace, you are the spokesperson of the sovereign whom you represent, i.e., Jesus Christ.
Your ministry is the ministry of reconciliation and your message is good news to those who do not know Jesus Christ.
“How beautiful are the feet of those who bring good news!” (Rom 10:15)
