Below are several bible verses that discuss our role as Christ followers in spreading the gospel and being His witness.
But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.
Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand. By this gospel you are saved, if you hold firmly to the word I preached to you. Otherwise, you have believed in vain. For what I received I passed on to you as of first importance that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures.1 Corinthians 15:1-4
You are the light of the world. A town built on a hill cannot be hidden. Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. In the same way, let your light shine before others, that they may see your good deeds and glorify your Father in heaven.Matthew 5:14-16
Then he said to his disciples, “The harvest is plentiful but the workers are few. 3 Ask the Lord of the harvest, therefore, to send out workers into his harvest field.”Matthew 9:37-39
2 Timothy 3:16-17
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, 17 so that the servant of God may be thoroughly equipped for every good work.
1 Peter 3:15
But in your hearts honor Christ the Lord as holy, always being prepared to make a defense to anyone who asks you for a reason for the hope that is in you; yet do it with gentleness and respect.
Be wise in the way you act toward outsiders; make the most of every opportunity. Let your conversation be always full of grace, seasoned with salt, so that you may know how to answer everyone.Colossians 4:5-6
Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on behalf of Christ, be reconciled to God.”2 Corinthians 5:20
