Colossians 1:24 Even as I write, I am glad of my sufferings on your behalf, as, in this mortal frame of mine, I help to pay off the debt which the afflictions of Christ still leave to be paid, for the sake of his body, the Church.✻
✻ ‘The afflictions of Christ’ have been understood by some commentators as being those which he suffers in his members, i.e. the Church (cf. Ac. 9.4), and particularly in St Paul himself. But the Greek verb shews that St Paul only represents himself as taking a share in the afflictions here referred to; and probably the metaphor is that of a poor man contributing to pay off a sum which a richer man has paid in advance. Thus the obvious meaning is that Christ’s sufferings, although fully satisfactory on behalf of our sins, leave us under a debt of honour, as it were, to repay them by sufferings of our own.
