I'd mentioned awhile back my grief over separation from some whom I love. The Lord guided me to a book on fasting. I've tried a water-only fast a couple of times before in my life, for just 24 hours, and became ill both times. This time, I tried only fruits and vegetables and juices for 24 hours. For me, that was much more tolerable. That same day or the next, the key person in that relationship prepared a gift with a note and a card for us. We also had a very pleasant phone call from that direction this week.
This was a major breakthrough Am I taking credit for it? No. I think the Lord who guided me to fast was eager to teach lessons both to me and to the other party.
I praise the Lord who answers prayers. I'm eager to continue fasting gently from time to time in the future, as the Lord guides. However, I'm absolutely positive that fasting isn't the key to the successful Christian life. Jesus himself is the key.
