“Tax collectors and prostitutes are entering the kingdom of God before you.”
Like all parables, Jesus’ parable of the father with two children invites hearers to judge themselves in making a judgement about the parable. The chief priests and elders see the first child as the one who does what the father (God in disguise) wants. This is the son who refuses to work in the vineyard but regrets his refusal and goes to work.
The leaders value the first child who actually works in the vineyard. In this way Jesus calls Israel’s leaders to do the same, to do God’s work in the temple that he has just cleansed of commerce. The leaders indict themselves for not leading people to God and for not tending to the blind and lame who sit in the temple courts.
Which son are you most like – I won’t but I do or I will but I don’t?
