It is primarily through scripture that we encounter God in the person of Jesus. These readings sometimes include familiar verses and stories. Certainly, they do repeat things the children may have studied in Sunday School. The advantage of daily Bible readings over a Sunday school lesson is that the children are responsible for reading and rereading passages about a particular character, thinking about that character on their own, and identifying some of their own feelings that may be shared with the character. Memorization of the scripture is important.
Children memorize many things.
My concern as a parent is that my children also know verses from the Bible that they will find themselves saying at times of hope, fear, joy, or despair. And, as they say those words, they will be aware of God's presence and love. It is my hope that each season, the scripture chosen and the activities suggested will add to the child's understanding of that time in the Christian year. Just as important as knowing the words of verses, the stories of biblical men and women, and the location of the books of the Bible is identifying the feelings and actions of those men and women and seeing how we today share those same feelings. Pick out a story that is important to you.
