Luk 18:5 yet because this widow troubles me I will avenge her, lest by her continual coming she weary me.’
Th motive behind the unjust judge giving justice was because the widow troubled him and would not give him rest. The only way to get rid of her was to grant her her petition. Thus she got justice done her by continual craving; she begged it at his door.
Jesus applies this for the encouragement of God’s people to pray with faith and fervency, and to persevere therein. Sometimes I wonder if we pray with such urgency, fervently, constantly, with desperation for certain needs. One reason God allows us to go through troubles is to open us to pray, Jas 5:13 “Is anyone among you suffering? Let him pray …” prayer especially with desperation is the means by which we get heaven’s attention, Jam 5:16-17, “16… The effective, fervent prayer of a righteous man avails much. 17 Elijah was a man with a nature like ours, and he prayed earnestly that it would not rain; and it did not rain on the land for three years and six months 18 And he prayed again, and the heaven gave rain, and the earth produced its fruit.” James gives an example of Elijah as an ordinary man armed with prayer, plowing through for breakthroughs. Hannah prayed with fervency for a child, she poured her heart to the Lord. Jacob wrestled with God all night and would not let Him go without the blessing
God for His glory has called us to a special task, Isa 62:6-7, “6 I have set watchmen on your walls, O Jerusalem; They shall never hold their peace day or night. You who make mention of the LORD, do not keep silent, 7 And give Him no rest till He establishes And till He makes Jerusalem a praise in the earth.” God says we should not give Him rest. That is, to be persistent with Him, as the widow with the unjust judge. “He gives us rest from sin and sorrow, that we may not rest from prayer. We must take no rest and give God no rest.”
