Albert Barnes on Luke 18:1

A parable. Mt 13:3.

To this end. To show this.

Always. At all times. That is, we must not neglect regular stated seasons of prayer; we must seize on occasions of remarkable providences--as afflictions or signal blessings--to seek God in prayer; we must always maintain a spirit of prayer, or be in a proper frame to lift up our hearts to God for his blessing, and we must not grow weary though our prayer seems not to be answered.

Not to faint. Not to grow weary or give over. The parable is de- signed to teach us that, though our prayers should long appear to be unanswered, we should persevere, and not grow weary in supplication to God.
