1 Corinthians 4:9

For... — This introduces the reason why he may well express the devout wish which he has just uttered for the coming of the kingdom of his Lord. The imagery of this passage would be easily understood by the Corinthians, familiar as they were with the arena. The writer, in a few striking phrases, pictures himself and his apostolic brethren forming the “last and most worthless” band brought forth to struggle and die in the great arena, where the whole world, including men and angels, sit, spectators of the fight. There is, perhaps, a slight contrast intended here between the Corinthians sitting by criticising, and the Apostles engaging actually in the struggle against evil — a contrast which is brought out more strikingly in the brief and emphatic sentence forming 1 Corinthians 4:10.
