While on board, both groups produce goods – with their God-given talents – and from God’s Own raw materials which He has loaned them. In spite of the reprobates’ constant complaints and unsuccessful attempts at repeated mutinies against God as the Owner of the ship, during the voyage He restrains them (and even His elect) from doing more damage than they do.
In addition, He bestows upon His elect alone His saving or special grace – and joy in their work. Not just for the voyage – but also for eternity. By God’s enabling, they lovingly help and patiently endure the reprobate crew-members – during the milleniums of that lengthy voyage.
