Luke 12:40

12:40 You also must be ready, because the Son of Man will come at an hour when you do not expect him.” ¹ 

Luke 14:27

14:27 Whoever does not carry his own cross ²  and follow ³  me cannot be my disciple.

[12:40]  ¹ sn Jesus made clear that his coming could not be timed, and suggested it might take some time – so long, in fact, that some would not be looking for him any longer (at an hour when you do not expect him).

[14:27]  ² sn It was customary practice in a Roman crucifixion for the prisoner to be made to carry his own cross. Jesus is speaking figuratively here in the context of rejection. If the priority is not one’s allegiance to Jesus, then one will not follow him in the face of possible rejection; see Luke 9:23.

[14:27]  ³ tn Grk “and come after.” In combination with the verb ἔρχομαι (ercomai) the improper preposition ὀπίσω (opisw) means “follow.”
