The unity of the books of the Bible is astounding when you realize the diversity within which it is united. It contains 66 different books written by several writers who lived in three different continents over a span of 1500 years. Most of them were not contemporaries and did not know each other. They were from different linguistic, economic, political, vocational and cultural backgrounds. There were kings, statesmen, prophets, scholars, army commanders, physicians, tax collectors, shepherds, fishermen, young and old, rich and poor. Their writings varied from historical narrative to book of law, poetic literature to prophetic proclamation. But in the midst of all these they all conveyed the same message, carried the same theme and centred on God’s plan of salvation for the humankind.
