I was thinking also the workers not hired were in stressful situations of waiting and not having means to pay for food,take care of their family etc. Similar to the daily stress in the lives of people not called yet , that have no hope that Christians that have God's knowledge and doing His will have. Brethren called earlier are blessed and should be thankful to be free of a lot of stress those that are called later are enduring.Yet we all can receive the same"penny".
