Prayer is the Key and Faith Unlocks the Door!

Jesus told his disciples a parable to show them that they should always pray and not give up.

..."And he spake a parable unto them to this end, that men ought always to pray, and not to faint; " Luke 18:1

The inspiration of this passage is to encourage us in spending time in prayer, with perseverance in it.  Not only in such sore times of trial and affliction are coming upon  us, but relentless, continued prayer.  

It is by means of this intense concentration that faith will be preserved.
