Jesus used a story to illustrate the need for constant prayer and to not lose heart:
“There was a city judge,” he said, “A very godless man who had great contempt for everyone. A widow of that city came to him frequently to appeal for justice against a man who had harmed her. The judge ignored her for a while, but eventually she got on his nerves.
“‘I fear neither God nor man,’ he said to himself, ‘But this woman bothers me. I’m going to see that she gets justice, for she is wearing me out with her constant coming!'”
Then the Lord said, “If even an evil judge can be worn down like that, don’t you think that God will surely give justice to His people who plead with Him day and night? Yes! He will answer them quickly!
But the question is: When I, the Messiah, return, how many will I find who have faith (and are praying)?”
So pray at all times in the Spirit, with all prayer and supplication.
Always be full of joy in the Lord…let everyone see that you are unselfish and considerate in all you do.
Remember that the Lord is coming soon.
Don’t worry about anything; instead, pray about everything; tell God your needs, and don’t forget to thank Him for His answers.
If you do this, you will experience God’s peace, which is far more wonderful than the human mind can understand. His peace will keep your thoughts and hearts quiet and at rest as you trust in Jesus.
Cast all your anxieties on Him, because He cares for you. The angel of the Lord encamps around those who fear Him, and He delivers them. God will sustain you when you give your burdens to Him.
