Perseverance in Faith - Luke 18:8

When the son of man cometh, shall he find faith on the earth?

This was spoken directly after the parable of the unjust judge. That parable speaks of the patience and unwearyingness of the petitioner. As a petitioner, we must not grow weary nor give up, lest when He comes he may find our faith to be lacking. The faith-filled petitioner will not give up simply because the Lord fulfills the petition in His own time-frame, but will be steadfast regardless of his perception of the timeliness of the answer or outcome of his efforts.
