We have done several of the Lifeguide studies. They have all been very good. We are a small church and these studies work very well for us. "Miracles" helps to remember the amazing miracles performed by Jesus and make us recognize that many of the things that happen to us are not mere coincidences.
This series was excellent for our Wednesday evening Bible studies. The lessons were well written with great opening examples and stories, and had generous thought-provoking questions that made discussions easy and natural. The leader's notes at the back of the book were very helpful and made preparation very smooth. I wholeheartedly recommend this for small to moderate sized groups.
