Lord, help me to pray always and not to lose heart.

The gospel reading from Luke 18:-1-8 was the first thing me eyes saw when I switched on my computer after a couple of hours of prayer and tears. That line was an arrow to my heart--"Then Jesus told them a parable about their need to pray always and not to lose heart." This is one of those times that I believe God whispers his presence in my life. This is how I hear God. Like Aslan breathing on the children. And the word today was not some sentimental quip, but rather an exhortation to persevere. God is not bound by time as I am. This life is merely a blip on the screen of eternity. So I must always pray and not lose heart, even when I don't see "timely" answers to prayer and when I lose awareness of God's activity in my life and the lives of those I love. Even when events don't make sense and I can't see "God's plan." This is difficult and requires a steadfast discipleship. I am tempted to doubt and despair. I have wondered why Jesus ended this discourse with the question--"And yet, when the Son of Man comes, will he find faith on earth?" I think I'm starting to get it. 
Oh, Lord, hear my prayer--help me to pray always and not to lose heart.
