The bible contains the mind of God, the state of man, the way of salvation, the doom of sinners, and the happiness of believers. It's doctrines are holy, it's precepts are binding, it's histories are true, and it's decisions are immutable. Read it to be wise, believe it to be safe, and practice it to be holy. It contains light to direct you, food to support you, and comfort to cheer you.
It is the traveler's map, the pilgrim's staff, the pilot's compass, the soldier's sword, and the Christian's charter. Here Paradise is restored, Heaven opened, and the gates of hell disclosed.
All in all... it is The Book of all Books!
