There is a very narrow view on what evangelism means and what it looks like in the Bible. Take a look at these descriptions.
The Lord’s followers who had been scattered went from place to place, telling the good news. – Acts 8:4
Then he sent them to tell about God’s kingdom and to heal the sick. – Luke 9:2
Soon after this, Jesus was going through towns and villages, telling the good news about God’s kingdom. His twelve apostles were with him – Luke 8:1
It is either telling the good news, or telling about God’s Kingdom or both. Even though we only see the announcement part in these verses we know that these lead to an invitation to enter that Kingdom by faith and repentance.
In fact, it is such a narrow view that it plays only a fraction in the life of the Church. Paul in fact had to refuse certain roles just so He could focus on evangelism.
Christ did not send me to baptize. He sent me to tell the good news without using big words that would make the cross of Christ lose its power. – 1 Corinthians 1:17
It also indicates that apologetics did not play a big part in evangelism either even though Paul did try to encourage people to respond.
What happened to those wise people? What happened to those experts in the Scriptures? What happened to the ones who think they have all the answers? Didn’t God show that the wisdom of this world is foolish? We know what it means to respect the Lord, and we encourage everyone to turn to him. God himself knows what we are like, and I hope you also know what kind of people we are. – 1 Corinthians 5:20; 2 Corinthians 5:11
Christian service or action or protests against injustices do not play a part in evangelism either.
A lot of people were now becoming followers of the Lord. But some of the ones who spoke Greek started complaining about the ones who spoke Aramaic. They complained that the Greek-speaking widows were not given their share when the food supplies were handed out each day. The twelve apostles called the whole group of followers together and said, “We should not give up preaching God’s message in order to serve at tables. – Acts 6:1-2
