Again, there was very little (really, nothing) in the main part of this message with which I would disagree. However, Meyer starts off by using as a jumping off point the story of the labourers in the vineyard found in the first part of Matthew 20. While the landlord in this story was generous and Jesus certainly is generous and we are to be imitators of Him, that isn't the point Jesus was trying to make by telling this story. The point of this story is that, whether you have served Jesus from the time you reached your age of accountability, from your twenties onward, from middle age onward, or whether you are an elderly person who has just come to Christ and may only serve Him here on Earth for a few years, we all receive the same thing promised all of us at the end: eternal life with God in His kingdom. The labourers couldn't do anything more to earn more money from the householder; they all agreed to work for a penny. We can't do anything more to earn what He promised us, either.
