[Luke 17:21] ...the kingdom of God will come into your midst (suddenly and apocalyptically from God). It will not come progressively as a synergistic insurrection from Israel’s inner rooms or wilderness areas. Unlike Barabbas (23:19), Jesus demands the embrace of non-violent martyrdom (9:23, 14:27). Only those disciples who renounce everything in this age (12:33; 14:33), putting their hope in God alone, will inherit the resurrection and eternal life “when the Son of Man comes” (18:8). This seems to be the apocalyptic faith that Jesus is cultivating in 17:20–21. - John P. Harrigan, Signs of Jewish Zealotry in Luke 17.20-21
