I just spent more than sixteen months praying that my unemployed husband would find work.  I had been at home for over 20 years homeschooling my children and taking care of our youngest son who has autism, but I found a part time job that brought in $400-700 per month, depending on how many hours I could get.  This was the only steady income we had.
 
I certainly did not content myself with asking once and then assuming that Steve just automatically had a job, which he clearly did NOT have.  I kept on seeking, asking, and knocking.  God saw to it that we did not lack anything we really needed, but it was only within the last week that Steve began working again.
 
I pray for my children all the time too.  I would never assume that a one-shot prayer for God to save them, sanctify them, protect them, and provide for them would be all that was needed.  I pray especially for my autistic son and for a son who has gone astray into bitterness and hatefulness, and I pray for the son and daughter who have none of these problems.  What else can I do?  I love them, and Jesus is the only One I want to go to for help, and the only One who truly CAN help us.  There are no other sources of blessing and provision.
 
And I pray for Jesus to come again soon.  Since the Rapture hasn't happened yet, I'm going to keep right on praying.  I don't believe that this means I lack faith.  If I lacked faith, I would have stopped praying.
