God is generous. He loves to be generous. He doesn’t carefully measure out the minimum he can get away with; he wants all of us to receive everything that we need.
God is like an employer who agrees a living wage for their full-time employees, and then decides to pay exactly the same salary to the part time staff, and even the occasional staff. God is like that. He loves to be generous.
However, God’s generosity can leave us feeling grumpy. Imagine an employer did agree to pay a living wage for their full-time employees, and then paid exactly the same salary to their part time staff, and even their occasional staff. Some would be working long hours, some short hours, and some hardly any hours at all - yet they would all take home the same pay at the end of the week. The full timers would quickly start complaining. They did in Jesus’ story, “The Workers in the Vineyard”. (Matthew 20:1-16)
God’s idea of equality and fairness is quite different from our own. He works on the principles of generosity and need (not of cost and reward). God loves to be generous, and he wants us to be generous too.
