Cover art for Set Your Sails lyrics by Future of Forestry

I agree with Lampala, but I think the first verse exclusively talks about those eleventh hour workers, saying "Don't miss the boat!" The parable to which it refers teaches us that the reward for those is the same as those who have been working all along. Surely, it's better to do something even if it is little than to do nothing at all in the service of the Lord because the reward is the same.
