EXPOSITION
Evangelism is a core duty for every Christian. It is the last command Jesus gave to His disciples. Therefore, it must be treated with reverence.
Evangelism is usually done in groups ( large or small) as many people seem comfortable with that. For this reason only few people seem to be interested in doing personal evangelism.
Personal evangelism is an individual evangelism. Philip went to preach to the Ethiopian Eunuch alone. You can also do same.
LESSON LEARNT: You can personally tell someone about Christ.
