fall and redemption
The Bible is a composite of separate books that have gone through a process of preservation to become a collection now known as the Bible.
These are individual books, each written by different individuals in different walks of life, living in different places, and in different times in history.
The significant signature that shines through all of the books is the unified story of the fall and redemption of mankind through the work of Jesus Christ.
2 Peter 1:21 For no prophecy ever came by the will of man: but holy men of God spoke, being moved by the Holy Spirit.
