It is always thus. Arthur W. Pink notes in his commentary: “It was thus with the woman at the well: until divine grace completed its work within her, she knew not the ‘gift of God’ (John 4:10). It was the same with the rich young ruler: ‘Good Master, what shall I do to inherit eternal life?’ (Luke 18:18). It was the same with the stricken Jews on the Day of Pentecost: ‘Men and brethren, what shall we do?’ (Acts 2:37). It was the same with the Philippian jailer: ‘Sirs, what must I do to be saved?’ (Acts 16:30). So it was with the prodigal son—‘Make me as one of thy hired servants’ (one who works for what he receives) was his thought (Luke 15:19).”1 None of those involved in these illustrations knew precisely what they must do or thought they must do, but they were certain that they had to do something.
