Study Union (Blakeslee) Lessons are examples of this trend. Both of them
are exceptionally good. Other courses have sprung up, being written and
used among boys here and there, and later worked together into a Bible
study scheme. The Boys' Bible Study Courses of the Young Men's Christian
Association are recognized as such. Then there is the present system of
Graded Bible Study of the International Sunday School Association.
Fifteen complete years of Graded Bible Study, from the fourth to the
eighteenth year, may now be used in the Sunday school. Great care has
been exercised in the selection of the material with the aim of fixing
definite ideals of Christian life and service. These courses are divided
as follows:
