The Precept NISS series is a wonderful way to get into God's Word on a daily basis. Your are directed to do inductive study (which means you are learning directly from the Word of God) with daily assignments that can be completed in under 30 minutes. There are also discussion questions at the end of each week for those who use the material with a small group or Sunday School class.
We walked through this study with our SS class of couples and it was a wonderful blessing to all! It's a great way to work through the study daily, and then come together weekly to discuss what God has shown to each person. I would highly recommend it to anyone!
