Luke 18:8

ποιήσει τὴν ἐκδίκησιν αὐτῶν. Isaiah 63:4; Psalms 9:12, “When He maketh inquisition for blood, He remembereth them, He forgetteth not the cry of the humble.” “Yet a little while,” Hebrews 10:37; 2 Peter 3:8-9. The best comment on the Parable and our Lord’s explanation of it may be found in His own Discourses, John 14:15.

ἐν τάχει. ‘Speedily,’ in reality (2 Peter 3:8) though not in semblance.

ἆρα εὑρήσει τὴν πίστιν; ‘Shall He find this faith on the earth?’ So St Peter tells of scoffers in the last days who shall say “Where is the promise of His coming?” 2 Peter 3:3-4; and before that day “the love of many shall wax cold,” Matthew 24:12; 2 Thessalonians 2:3. Even the faith of God’s elect will in the last days be sorely tried (Matthew 24:22). Ἆρα is like the Latin num. Comp. Galatians 2:17 ἆρα Χριστὸς ἁμαρτίας διάκονος;
