Luke 18:6-8

Jesus proceeded to apply the parable for His disciples. Listening carefully to the judge’s words was important because only then could the disciples see that Jesus was teaching by contrast. God would never respond to a cry for help as this judge did. In view of His character disciples can count on Him giving them the protection they need. The term "elect" is a reminder that He has chosen those who call to Him (cf. Matthew 22:14; Mark 13:20; Mark 13:22; Mark 13:27). This is another reason He will respond to their call. The widow was a stranger to the unjust judge. Moreover Jesus said He would not delay to give the protection His disciples need.

Though God has allowed some disciples who call on Him for help during persecution to die, He nevertheless gives added grace to them (cf. 2 Corinthians 12:9). The justice He will provide speedily is protection from the attacks of spiritual opponents (Luke 18:3). It is justice because the disciple is suffering unjustly when he or she stands for Jesus and consequently experiences persecution.

"God longs to vindicate the saints, and he will do so. When he does, his justice will be swift and sure, and our suffering will seem short-lived compared to the glory to follow. In the meantime he protects us." [Note: Bock, Luke, p. 455.]

Jesus’ final question suggests that there will be comparatively few on the earth who have remained faithful and who believe that He will return (Luke 17:22 to Luke 18:1). [Note: See David A. Mappes, "What Is the Meaning of ’Faith’ in Luke 18:8?" Bibliotheca Sacra 167:667 (July-September 2010):292-306.] The Second Coming is in view, not the Rapture. The phrase "Son of Man" links this question with Jesus’ former teaching about His return (Luke 17:22; Luke 17:24; Luke 17:26; Luke 17:30). This is all the more reason disciples need to keep praying. Prayer not only secures God’s help during persecution, but it also demonstrates faith in God.

This parable then is an encouragement for disciples who experience opposition for their faith during the inter-advent age. We should continue to ask God for protection from those who oppose us for our commitment to Jesus Christ. God will respond speedily by giving us the help that we need. This will result in the continuing demonstration of faith in God when He is visibly absent from the world during this period. The parable is an exhortation to persevere in the faith rather than apostatizing (i.e., turning away from it). God will vindicate His elect at the Second Coming (cf. Psalms 125:2-3; Revelation 6:9-11). That will be His ultimate answer to these prayers of His people, but immediate help before that coming is primarily in view in this parable.
