The parable describes a father who asks his two sons to work in the vineyard. The first son refuses but later changes his mind and goes. The second son says he will go but does not. Jesus says the tax collectors and prostitutes who repent will enter God's kingdom before those who refuse to repent like the second son. The document then discusses the Ten Commandments and Jesus' commandment to love God and others, and the Great Commission to make disciples of all nations.
