Mark 13:21-23

Jesus repeated His warning about people who will claim to be the Messiah (cf. Mark 13:5-6) so His disciples would not believe them. "If possible" (Mark 13:22) does not imply that the elect will inevitably continue to believe in Jesus and follow Him faithfully. If that were so, Jesus’ repeated warnings would be meaningless. It means that the false Messiahs will do miracles with the intent of leading the elect into error if they, the false Messiahs, can (cf. 2 Timothy 3:1-15). In view of this possibility, Jesus’ disciples need to be discerning (Gr. blepete, Mark 13:23).
