For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— (Ephesians 2:8)

“For the kingdom of heaven is like a landowner who went out early in the morning to hire workers for his vineyard. He agreed to pay them a denarius for the day and sent them into his vineyard. “About nine in the morning he went out and saw others standing in the marketplace doing nothing. He told them, ‘You also go and work in my vineyard, and I will pay you whatever is right.’ So they went. “He went out again about noon and about three in the afternoon and did the same thing. About five in the afternoon he went out and found still others standing around. He asked them, ‘Why have you been standing here all day long doing nothing?’ “‘Because no one has hired us,’ they answered. “He said to them, ‘You also go and work in my vineyard.’ “When evening came, the owner of the vineyard said to his foreman, ‘Call the workers and pay them their wages, beginning with the last ones hired and going on to the first.’ “The workers who were hired about five in the afternoon came and each received a denarius. So when those came who were hired first, they expected to receive more. But each one of them also received a denarius. When they received it, they began to grumble against the landowner. ‘These who were hired last worked only one hour,’ they said, ‘and you have made them equal to us who have borne the burden of the work and the heat of the day.’ “But he answered one of them, ‘I am not being unfair to you, friend. Didn’t you agree to work for a denarius? Take your pay and go. I want to give the one who was hired last the same as I gave you. Don’t I have the right to do what I want with my own money? Or are you envious because I am generous?’ “So the last will be first, and the first will be last.” (Matthew 20:1-16)

not by works, so that no one can boast. (Ephesians 2:9)

If someone else thinks they have reasons to put confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; as for zeal, persecuting the church; as for righteousness based on the law, faultless. But whatever were gains to me I now consider loss for the sake of Christ. What is more, I consider everything a loss because of the surpassing worth of knowing Christ Jesus my Lord, for whose sake I have lost all things. I consider them garbage, that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which is through faith in Christ—the righteousness that comes from God on the basis of faith. (Philippians 3:4b-9)

All of us have become like one who is unclean, and all our righteous acts are like filthy rags; (Isaiah 64:6a)
