Thanks for your responses. Yeah, I'm not sure that guilt and obligation are healthy motivators to share the good news. Certainly willing obedience to God is a good motivator and also love and concern for the lost are.
Does anyone know of any other Bible verses that are used to promote the universal evangelism doctrine?
It’s not only apostles that have the ministry of reconciliation and the role of Christ’s ambassadors—all believers do! Verses that reflect on this ministry of witness for all believers include:
Acts 1:8 (NLT)
But you will receive power when the Holy Spirit comes upon you. And you will be my witnesses, telling people about me everywhere—in Jerusalem, throughout Judea, in Samaria, and to the ends of the earth.”
2 Corinthians 5:18-20 (NLT)
And all of this is a gift from God, who brought us back to himself through Christ. And God has given us this task of reconciling people to him. 19 For God was in Christ, reconciling the world to himself, no longer counting people’s sins against them. And he gave us this wonderful message of reconciliation. 20 So we are Christ’s ambassadors; God is making his appeal through us. We speak for Christ when we plead, “Come back to God!”
Matthew 5:14-16 (NLT)
“You are the light of the world—like a city on a hilltop that cannot be hidden. 15 No one lights a lamp and then puts it under a basket. Instead, a lamp is placed on a stand, where it gives light to everyone in the house. 16 In the same way, let your good deeds shine out for all to see, so that everyone will praise your heavenly Father.
1 Peter 3:15 (NLT)
Instead, you must worship Christ as Lord of your life. And if someone asks about your Christian hope, always be ready to explain it.
Philippians 2:14-16 (NLT)
Do everything without complaining and arguing, 15 so that no one can criticize you. Live clean, innocent lives as children of God, shining like bright lights in a world full of crooked and perverse people. 16 Hold firmly to the word of life; then, on the day of Christ’s return, I will be proud that I did not run the race in vain and that my work was not useless.
Colossians 4:5-6 (NLT)
Live wisely among those who are not believers, and make the most of every opportunity. 6 Let your conversation be gracious and attractive so that you will have the right response for everyone.
1 Peter 2:9 (NLT)
But you are not like that, for you are a chosen people. You are royal priests, a holy nation, God’s very own possession. As a result, you can show others the goodness of God, for he called you out of the darkness into his wonderful light.
