God employs human beings…
“For the kingdom of heaven is like a landowner who went out early in the morning to hire labourers for his vineyard. Now when he had agreed with the labourers for a denarius a day, he sent them into his vineyard. And he went out about the third hour and saw others standing idle in the marketplace, and said to them, ‘You also go into the vineyard, and whatever is right I will give you.’ So they went. Again he went out about the sixth and the ninth hour, and did likewise. And about the eleventh hour he went out and found others standing idle and said to them, ‘Why have you been standing here idle all day?’ They said to him, ‘Because no one hired us.’ He said to them, ‘You also go into the vineyard, and whatever is right you will receive.” Matthew 20: 1-7
“The proclamation of the gospel is the only means in which God can employ human beings as His instrumentalities for the salvation of souls. As men, women, and children proclaim the gospel, the Lord will open the eyes of the blind to see His statutes, and will write upon the hearts of the truly penitent His law. The animating Spirit of God, working through human agencies, leads the believers to be of one mind, one soul, unitedly loving God and keeping His commandments–preparing here below for translation” Review Herald Oct. 13, 1904
