A few years ago, because of cutting, Indian Paintbrush almost disappeared from our neighborhood roadside. It's persistence has paid off with some beautiful spreads this year.
In Luke 11:1-13, Jesus encourages us to hang in there with our praying. Torturing ourselves trying to figure out why Jesus is not answering our prayers distracts us from the sustained work of petition. I often ask God specifically for what I want. At the same time I pray, "I want to want what You want."
