I am blessed when friends stop and pray. On the spot. My husband was encouraged when his friend said a quick prayer for him. Right there at the school picnic. I found a magazine open to this article when going through papers recently:
Don't delay: The gift of on-the-spot prayer by Art Hunt.
You can read the article online if you sign up for an account at NavPress. Or borrow my copy.
Therefore, confess your sins to one another and pray for one another, that you may be healed. The prayer of a righteous person has great power as it is working. James 5:16 ESV
