The story of Paradise Lost by John Milton details the disobedience and fall of humanity from the grace of God. God predetermined all that was and all that will follow His creation. The major themes of the poem are obedience to God, the nature of the universe, and ultimately the fall of humanity. These themes will be further explained through Milton's explanation of light and darkness. Milton's conversations between Satan, Beelzebub, Adam, and Eve illustrate the difference between their conflicting views of good and evil. Milton displays his pride by stating that he is attempting something that has never been done before by writing this poem, he is asking for help from his muse. Themes are essential and often universal ideas explored in a literary work. This disobedience to God will provide the structure of Milton's poem. Throughout his poem he invokes the help of his muse as a source of motivation. The first line illustrates Milton's main theme: "man's first disobedience" (1.1). This disobedience refers to Adam and Eve eating the forbidden fruit and thus falling out of favor with God. Satan refuses to ask for forgiveness, which is why he will stay in hell. Adam and Eve repent of their sins and ask for forgiveness in hopes of being forgiven. They acknowledged their disobedience to God, and through their repentance, man's salvation will follow. The second theme of Paradise Lost is the nature of the universe, providing a tangible interpretation by Milton. It illustrates the separation of Heaven above, earth in the middle and hell below. It is the natural order of the Christian worldview that constitutes the foundation of the faith. Hebrews 1:3 details the radiance of God's glory and the exact imprint of his nature, and it supports the universe by the middle of the paper...... connections between heaven and hell, God and Satan is therefore good and bad. John 8:12 conveys the power of His light as Jesus spoke to them saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.” The light of the world in this verse refers to the grace of God. The non-existence of light in Hell expresses the message that the existence and grace of God are not present in Satan or in Hell. Milton's creation of this Christian epic provides the ethical actions upon which the world was built. The plot of Satan and Beelzebub to overthrow heaven and the disgrace of Adam and Eve describe the Christian's daily struggle against free will. God's ultimate plan is manifested in the sacrifice of his only son. Salvation is achieved through devotion and respect to God, but if one feels remorse, one can experience compassion, deliverance and grace..
