Now Jesus was telling the disciples a parable to make the point that at all times they ought to pray and not give up and lose heart,Luke 18:1 AMP

...The earnest (heartfelt, continued) prayer of a righteous man makes tremendous power available [dynamic in its working].James 5:16B AMPC

This is a short charge to stir you up and encourage you to pray. No matter the circumstance you're in, know that what prayer cannot solve more prayer will!

Pray!
