CHURCH - This is a particular group of christians.
                - They are the ministers of the christian faith.A christian is the person who believes in the teachings of  Jesus Christ and practices His teachings.
Leslie Woodson, (1973) in Evangelism for today's Church, says that, " the Christian has a Christ to share with men and women who embrace a non-Christian religion as well as those who acknowledge no religion at all."

When Christ is shared to the unbelieving as was done by the Apostles even with the backing of God among the results recorded included conversions of many and at times riots form those who felt they did not want their values, worldview, attitudes, destiny, character among others to changes.2 CORINTHIANS 5:17 reminds as that  "...if anyone is in Christ, he is a new creation; the old has gone,the new has come!" Those that rioted at Thessalonica cried out that the people who had turned the world upside down [who had caused trouble everywhere] had gone to their city. ACTS 17:6
