Anthony Gammage – Matthew 21:28-46
And when he entered the temple, the chief priests and the elders of the people came up to him as he was teaching, and said, “By what authority are you doing these things, and who gave you this authority?”
“What do you think? A man had two sons. And he went to the first and said, ‘Son, go and work in the vineyard today.’ And he answered, ‘I will not,’ but afterward he changed his mind and went. And he went to the other son and said the same. And he answered, ‘I go, sir,’ but did not go. Which of the two did the will of his father?” They said, “The first.” Jesus said to them, “Truly, I say to you, the tax collectors and the prostitutes go into the kingdom of God before you.
For John came to you in the way of righteousness, and you did not believe him, but the tax collectors and the prostitutes believed him. And even when you saw it, you did not afterward change your minds and believe him.
“Hear another parable. There was a master of a house who planted a vineyard and put a fence around it and dug a winepress in it and built a tower and leased it to tenants, and went into another country. When the season for fruit drew near, he sent his servants to the tenants to get his fruit. And the tenants took his servants and beat one, killed another, and stoned another. Again, he sent other servants, more than the first. And they did the same to them. Finally, he sent his son to them, saying, ‘They will respect my son.’ But when the tenants saw the son, they said to themselves, ‘This is the heir. Come, let us kill him and have his inheritance.’ And they took him and threw him out of the vineyard and killed him. When therefore the owner of the vineyard comes, what will he do to those tenants?” They said to him, “He will put those wretches to a miserable death and let out the vineyard to other tenants who will give him the fruits in their seasons.”
The stone that the builders rejected has become the cornerstone. This is the LORD’s doing; it is marvelous in our eyes.
Therefore I tell you, the kingdom of God will be taken away from you and given to a people producing its fruits. And the one who falls on this stone will be broken to pieces; and when it falls on anyone, it will crush him.”
1 Peter 2:4–10
As you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house, to be a holy priesthood, to offer spiritual sacrifices acceptable to God through Jesus Christ. For it stands in Scripture:
“Behold, I am laying in Zion a stone, a cornerstone chosen and precious, and whoever believes in him will not be put to shame.”
So the honor is for you who believe, but for those who do not believe,
“The stone that the builders rejected has become the cornerstone,” and “A stone of stumbling, and a rock of offense.”
They stumble because they disobey the word, as they were destined to do. But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.  Once you were not a people, but now you are God’s people; once you had not received mercy, but now you have received mercy.
