Hold fast to the Bible as the sheet anchor of your liberties. Write its precepts in your hearts, and practice them in your lives.

The Bible is the one supreme source of revelation of the meaning of life, the nature of God, and spiritual nature and needs of men.

The fundamental basis of this nation's laws was given to Moses on the Mount.

Inside the Bible's pages lie all the answers to all of the problems man has ever known . . .
