What does it mean to be known by Christ?

In the context of Luke 13:25-27, when Jesus said, 'I know you not whence you are,' He refers to an intimate and personal knowledge of His sheep—those whom He has chosen for salvation. This knowing is not superficial; it signifies a deep relationship fostered by grace and is rooted in God's purpose from eternity. It expresses the security that believers have in being recognized and loved by Christ, highlighting the biblical understanding that the knowledge of God entails a profound connection that distinguishes the elect from the non-elect. Thus, being known by Christ offers believers assurance of salvation due to His unwavering commitment to them.
