"The father went to the second son with the same command, “Go work today in my vineyard.” This son made reply, “I go, sir,” but he went not. COL 275.1"
"And he came to the second, and said likewise. And he answered and said, I go, sir: and went not."
EGW directly references and paraphrases Matthew 21:30.
"In this parable the father represents God, the vineyard the church. By the two sons are represented two classes of people. The son who refused to obey the command, saying, “I will not,” represented those who were living in open transgression, who made no profession of piety, who openly refused to come under the yoke of restraint and obedience which the law of God imposes. But many of these afterward repented and obeyed the call of God. When the gospel came to them in the message of John the Baptist, “Repent ye; for the kingdom of heaven is at hand,” they repented, and confessed their sins. ( Matthew 3:2 .) COL 275.2"
"And saying, Repent ye: for the kingdom of heaven is at hand."
EGW directly quotes Matthew 3:2.
"For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen it, repented not afterward, that ye might believe him."
EGW directly references Matthew 3:2 and connects it to the repentance of those who initially refused God's call, aligning with the parable's interpretation.
