“If your eye causes you to sin, tear it out. It is better for you to enter the kingdom of God with one eye than with two eyes to be thrown into hell [Gk gehenna], ‘where their worm does not die and the fire is not quenched.’” (Mark 9:47-48)

The messianic kingdom is clearly antipodal to the lake of fire/gehenna in the age to come (cf. Mt 8:12; 13:42; 25:34, 46, etc). So if the kingdom is "already not yet," what’s up with Gehenna? Why isn't it also being "spiritually" realized? - John P Harrigan
