Jesus gave believers the “Great ComMISSION” to make disciples. This is a LIFEstyle, fellowship, and process of helping others “grow up in all things into Him who is the head — Christ.” (Eph. 4:15). It’s laying down one’s life for another in love, like Jesus (Jn. 15:13). Maturity is realized through reproduction. If a believer lives like Jesus, and is reproducing other believers that live like Jesus — that’s a mature believer — a member of the bride of Christ. (Rev. 19:7-8).
