The phrase "will defend, will give defence" conveys His intent to enact both justice and mercy for their lives against the adversities and tribulations that will occur at Christ's return, represented here as foes targeting the believers or the chosen people of God.
The “chosen” refers to those loyal to God, particularly the genuine disciples of Jesus Christ, who are termed elect because God has selected them for salvation and eternal life from among the unbelieving. They embody the true children of God (1 Thess. 1:4, Col. 3:12, 1 Pet. 1:2, Eph. 1:4). This imagery draws upon the idea of choosing one nation, the Jews, from among all the nations as God’s treasured people. The phrase "Crying to Him day and night" emphasizes the fervent prayer of believers, highlighting their steadfastness and perseverance in seeking God.
“Though slow to defend them” indicates that God, while testing their faith, does not promptly grant their requests in prayer, often allowing temptations and hardships to persist, seemingly neglecting them. However, He never truly abandons them and provides aid, especially in contrast to the unjust judge's prolonged refusal to assist the widow. Consistency and persistence in prayer are essential in these circumstances.
“But the Son of Man,” etc. Despite the certainty that God will quickly safeguard His elect, will He find such faithful individuals who possess the steadfastness and persistence in prayer that is essential? There is no concern about God failing to uphold His promises of protection; rather, the worry lies in whether His elect will remain unwavering and patient in prayer, resisting despair under trials. Ultimately, this saying suggests that the greater risk is that Christians may falter in their faith rather than that God would withhold His assistance to the faithful. In essence, it emphasizes God’s unwavering and faithful commitment to fulfilling His promises regarding the protection of His devoted ones, rather than predicting a decline of faith on Earth before the Messiah’s return.
“Having come” refers to the coming of the Messiah during judgment upon the Jewish people at the fall of Jerusalem and also pertains to the second coming of Jesus Christ at the end of time, with the first coming serving as a foreshadowing of the second. Therefore, this term must be understood in both contexts. The term “faith” is frequently referenced in Scripture as denoting religion in general, encapsulating the essence of faith. However, within the context provided, it holds a more specific meaning. By instructing His disciples that amid significant trials and temptations, God would protect His chosen ones through their steadfast prayer in accordance with His promises, the Lord inquires whether there will be sufficient perseverance and steadfastness in prayer among them. Will they demonstrate the strength and vitality of faith required to maintain such resolute and constant prayer? Will He discover His followers vigilant in prayer and steadfast in faith, mirroring His divine commitment to aid and protect them through difficulties?
