Luke 18

"1 Then He spoke a parable to them, that men always ought to pray and not lose heart. 7 And shall God not avenge His own elect who cry out day and night to Him, though He bears long with them? 8 I tell you that He will avenge them speedily. Nevertheless, when the Son of Man comes, will He really find faith on the earth?"

Comforting to know what we will be avenged by God if we continue to bug God and pray to Him. However, the last sentence caught my eye, "Will He really find faith on the earth?" Even thought this was not written as a condition prior for God to avenge us, it brings out a concern to if we will be avenged if our faith isn't there. From this passage, it seems like God will avenge us anyway. However, the sad part about the lack of faith is included perhaps to remind us to keep our faith so that God won't be sad when He finds no faith at His return.
