All of the Old Testament was written to let us know about Jesus Christ. This is the purpose of the New Testament also. All that was written before the man Jesus was born, the man whose Spirit was and is and always will be God, was written to herald His coming All that has been written after is to tell those who will, how to follow Him and in the end, be like Him and to those who will not, what their fate is aside from the mercy afforded those who will accept it by the blood price Jesus paid.
