This booklet examines the nature of the relationship between believer and unbeliever. What does it mean to be separate from unbelievers, as we are told in 2 Corinthians 6:17?It obviously cannot mean that Christians are not to meet, talk to, eat with, work with, or live alongside to those who are not Christians. That would require total isolation and segregation in self-contained colonies of some sort! Besides, the Lord Jesus has commanded His people to go into all the world and preach the gospel (Mark 16:15), and the most effective way to present the gospel to unbelievers is to live out its characteristics before them in everyday life.To be separate is to be different: to live among people yet be distinct from them, to get close to them without being identified with them in aims, habits, partnerships or fellowships. It means never taking on an unequal yoke, a scriptural term (2 Corinthians 6:14) which we explore in this booklet.About the Author: John Ritchie started the publishing company named after himself many years ago and printed many helpful Christian books during his lifetime.
