A 3-minute retreat? Never heard of it. Neither had I, but I love it and frequent it often.
If you are like me, it seems very hard to find time to just be. If we are to hear God, and take care of our one of a kind masterpiece that God created (us), we need to time to rest and drink in a good cup of coffee and all the Lord has to say.
My prayer time has changed over the years. At times it was very regimented, almost WAY too much. Other times, I have to admit it’s been a bit willy nilly. Other times it’s frankly been lame, or even seemingly non-existent.
