What does the Bible say about separation in Christianity?

The concept of separation in Christianity is deeply rooted in Scripture, where the term signifies a boundary set by God. This separation is not merely a choice of religious affiliation but is a divine act where individuals are called out of darkness into light by Christ. Paul, for instance, describes his own separation as a divine calling that excluded him from his previous associations. This reflects the biblical truth that true followers of Christ cannot find fellowship with those who walk in darkness. In Matthew 10:34, Jesus states that His coming brings division, indicating that the call to follow Him often leads to separation from non-believers, even within families.
