Luke 19:18-19

The second servant had also been faithful, but he had only earned a 500 percent return on the master’s investment. He did not receive as much commendation as the first servant or as much reward, but his reward was also proportionate to his service. This shows that rewards will vary depending on a servant’s effectiveness.

"The reward is not rest, but the opportunity for wider service." [Note: Morris, p. 275.]
