How is the concept of Mashiach manifest in the Torah itself? What is the purpose of holiness? What is evil? Why did G-d create it? What effect does impurity have? G-d's ultimate objective is that Man should inherit an eternal world. Anything used to achieve that objective is called mashiach. Suffering is an involuntary purification, whereas repentance is a voluntary purification - the choice of which we go through is up to us. Everything which happens in the world is in some way connected to the processes of holiness and purity. Survey stories through the Torah and history and examine where the Messianic processes are holding at each specific point. Why did G-d "hire" the Satan? Understand the Satan's role and why it is to our ultimate benefit.
