Evangelism is the act of sharing one’s beliefs or promoting a particular religious message in order to bring others to that faith. It involves actively engaging with people and spreading the message through various means, such as conversations, events, or literature [pamphlets and printed texts promoting something]. For example, when a person goes door-to-door to talk about their religion and invite others to attend their church, they are practicing evangelism.
Very Simple Definition:
Evangelism is telling others about your religion to try to make them believe the same things. For example, when you tell a friend about your church and ask them to come with you, that’s evangelism.
