{Be ye steadfast, unmovable} (hedraioi ginesthe,
ametakin(8874)oi). "Keep on becoming steadfast, unshaken." Let the
sceptics howl and rage. Paul has given rational grounds for faith
and hope in Christ the Risen Lord and Saviour. Note practical
turn to this great doctrinal argument. {Work} (ergon), {labour}
(kopos, toil). The best answer to doubt is work.
