Evangelism is an important part of Christianity. A large portion of Christianity is known as “evangelical.” Some preachers are called “evangelists.” Many Christians have been told it is important for them to “evangelize.” What does this mean?
To evangelize is to tell someone good news. A messenger that brought a report of victory in battle brought the evangelion, the “good news.” In the Greek world, an evangelion was a message from the gods. In the Roman world the announcement of the birth of an emperor was good news. Any good news was an evangelion. To evangelize is to tell the evangalion.
The first mention of the good news- usually translated “gospel”- in the New Testament is found in the Gospels. John the Baptist and Jesus preached the gospel of the kingdom. Jesus sent out His disciples to preach the gospel to all the communities of Israel. After Jesus’ death and resurrection He sent His disciples to go into the entire world and “preach the gospel to every creature.” (Mark 16:15)
The good news was prophesied in Isaiah 61:1-2, “The Spirit of the Lord GOD is upon me; because the LORD hath anointed me to preach good tidings unto the meek; he hath sent me to bind up the brokenhearted, to proclaim liberty to the captives, and the opening of the prison to them that are bound; To proclaim the acceptable year of the LORD, and the day of vengeance of our God; to comfort all that mourn;” Jesus quoted Isaiah 61 in His hometown of Nazareth to announce that He was the prophesied Messiah.
The good news as described in the Bible is not just a message, it is a person. The good news is Jesus. The content of the message of Jesus is defined by the Bible and contains several objective, historical features. The good news is the truth of Jesus’ deity, death on the cross and resurrection. The gospel is defined in 1 Corinthians 15:3-4, “For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:”
To evangelize is to tell others the truth of Jesus. He is good news indeed. To evangelize is to tell others the gospel. This is why Isaiah 52:7 says, “How beautiful upon the mountains are the feet of him that bringeth good tidings, that publisheth peace; that bringeth good tidings of good, that publisheth salvation; that saith unto Zion, Thy God reigneth!” This is why Paul quoted Isaiah when he wrote to the Romans, “For whosoever shall call upon the name of the Lord shall be saved. How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things!” (Romans 10:13-15)
