The Parable of the Workers in the Vineyard is found in Matthew 20:1-16. In this parable Jesus illustrates that salvation is for everyone who wants it and the measure of salvation is the same for everyone no matter how long you have been saved. There isn't more salvation for those who have been saved longer than others. We cannot apply the earthly principles of seniority or first in line to the Kingdom of Heaven. Our earthly rules do not apply. It's God's rules and principles that apply and we need to get out of our own way of understanding and apply God's way. There are no bragging rights for older Christians over new Christians. Peace is peace. You cannot get a bigger slice of peace. There is no salvation times two or half of everlasting life. We all get the same. Isn't that wonderful? Why would new Christians want to join the Kingdom of Heaven if they got less joy and less peace? We should want everyone to be saved and everyone to have peace, joy, and everlasting life the same as we have. In an earthly world where we are not all treated equally and we do not all have the same resources and level of access, these things can make us feel less than or left behind. There is joy in knowing that the God's Kingdom does not operate the same because the measure is all the same. The message of the last will be first and the first will be last is Jesus' way of saying we all can enter the Kingdom of Heaven with the same abundance as every other saved soul.
