A powerful symbol mentioned at the beginning (Gen. 1: 3) and the end (Rev. 22: 5) of the Bible for goodness and truth. Hence the Law is described as ‘a light for my path’ (Ps. 119: 105); ‘the day of the Lord’ was expected to be light (Amos 5: 18), and people were disconcerted when the prophet predicted darkness. Light and darkness are commonly encountered as antitheses in the Dead Sea scrolls, and this is a feature which they share with the gospel of John; Christ is described as the light of the world (John 8: 12), sent by God who himself is light (1 John 1: 5), and those who are sent by Christ become in turn the light of the world (Matt. 5: 14).
