Jesus lived, worked, and ministered in the world and he calls us to do the same.
The workplace is your mission field.
After the Last Supper, Jesus was reflecting on his ministry with the disciples when he said in John 16:28, “I came from the Father and entered the world.”
Later, when praying to his Father, Jesus went further and included us in his prayer. Jesus says in John 17:15, “My prayer is not that you take them out of the world.” He prayed that we not be taken out of the world. He wants us in the world just like he was in the world.
Jesus spent most of his earthly ministry in what we would refer to as the streets. He was a marketplace minister. Jesus made daily contact with all sorts and conditions of mankind.
Two gospel passages make this clear. Matthew 9:10 states, “While Jesus was having dinner at Matthew’s house, many tax collectors and ‘sinners’ came and ate with him,” and Luke 15:1, “Now the tax collectors and ‘sinners’ were all gathering around to hear him.”
Jesus still has work to do here and now and his method is to do it through us, his church. As a Christian who goes to a job five days a week, you are Christ’s representative at your place of employment. The workplace is most definitely in the world and it is your mission field. It is literally within commuting distance from your home and you are there five days a week.
Be salt and light to others.
One way to be a witness to your co-workers is to simply be God’s salt and light to them.
In the first verses of Matthew 5, which is part of the Sermon on the Mount, Jesus describes what Christians are like, and later in the same chapter, in Matthew 5:13-14, Jesus describes what Christians do. This is where he declares:
“You are the salt of the earth … You are the light of the world.”
As a Christian, you are salt which means you inhibit decay and add flavor. You are light, which means you dispel the darkness and illuminate the way so others can see. These two metaphors describe the basics of your evangelistic ministry in the workplace.
Your salt and light can be seen and experienced by others. It is on display every hour of every day. God has already transformed you, and he is ready to transform those around you.
Notice in Matthew 5 that Jesus did not give you “Six Steps to Evangelizing Your Co-workers” or anything similar. There are no presentations to memorize and a degree in theology is not required—just manifest the character of Jesus Christ and love people the same way he loves people.
God can use your changed life as an example for those who do not know him. Be God’s salt and light to others.
