"And he spake a parable unto them to this end, that men ought always to pray, and not to faint;
Saying, There was in a city a judge, which feared not God, neither regarded man:
And there was a widow in that city; and she came unto him, saying, Avenge me of mine adversary.
And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man;
Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me.
And the Lord said, Hear what the unjust judge saith.
And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?"
Luke 18:1-7
I like Christ explaining here that we should keep praying and not give up. God will answer our prayers in his own time, and in his own way, but he is hearing us, and does care about what we say. We have to make sure that we aren't asking for something that God doesn't want, or asking for a bad reason, but if it is a good thing and within God's will, then God will answer it somehow, within his own time, but continuing to ask isn't going to annoy God. Continuing to pray and being open to listen to what God has to say can only help us learn more, and God will help us understand whatever answer we receive.
Today, let's pray in faith for good things, and for understanding of the Lord's will so that our petitions can be part of the solution and help build up the kingdom of God.
