"Brother and Sister I have been faithful burden bearers in the cause of God, and now their children should not stand back and let the burdens rest so heavily upon them. It is time that the powers of the less-worn minds of the children should be exercised and they work more especially in the Master's vineyard. 3T 57.4"
"For the kingdom of heaven is like unto a man that is an householder, which went out early in the morning to hire labourers into his vineyard."
EGW uses the metaphor of working in God's cause, specifically mentioning the 'Master's vineyard,' which directly echoes the parable in Matthew 20:1. The idea of laborers working in the vineyard connects the two passages.
