1. Telling people “I’ll pray for you” without actually praying for them. Guilty as charged. I can’t think of anybody who hasn’t done this at one time or another. And while most of us don’t actually mean to forget, it’s probably best that we just set aside time on the spot to pray for people. Are we really so busy that we can’t stop and pray for someone’s needs? We need to make sure we are fulfilling our duties as Christians and actually follow through with them. One prayer could be the tipping point to someone coming to know the love of God. Don’t miss the opportunity to speak life into someone because you don’t think you have time.

Side note:
When someone ask you to pray for them it is handy to have a notebook ready. Write down their name, just their first name will do if they want to remain anonymous, and the reason they want prayer to make sure that you don’t forget.
I also have had business cards that have my contact info, and my website address on them. That way they can contact you with questions about your faith, or to give you an update on their prayer request.
