The believer should imitate the persistent widow, also referred to as "importunate".
According to Luke, the parable of the persistent widow teaches the disciples to "pray always without becoming weary" (Lk 18:1).
This lesson follows Jesus' discussion on the coming of the kingdom, where he states that the time is near "when you will desire to see one of the days of the Son of man, and you will not see it" (Lk 17:22).
The current times are described as "betwixt and between", with the kingdom being both already present and yet to come.
The proper disposition of the disciple is to pray without losing heart, without giving up.
The parable may also be intended to be humorous.
