Is there really a battle between Jesus and Satan ? The Bible tells about the existence of Jesus and satan (adversary). Satan used to be one of archangels, a beautiful angel,whose beauty got into him, that he decided to be like God, that he planned to ascend to the place of God (from book of Isaiah). According to the book of Revelation, Satan was able to deceive a third of the angels who are later called demons.
Satan appeared in the garden of Eden as the serpent and beguiled Eve into eating the forbidden fruitand Eve convinced Adam to eat too and so sin came into the world, and passed on to every human being.
Jesus came to earth as a human being to destroy the work of the enemy(Satan or serpent) and to save His people from sin and from death.
At this point, we physically don't see Jesus and Satan battling but it is happening in the spiritual realm.
This battle is being waged in our flesh or body, in our soul, in our spirit. Wow , again the reader may ask how do i know this ?From reading the Bible and observing my own life and others. The New Testament also call this the battle of the flesh and Spirit.
If you have not accepted Jesus Christ as your Lord and Savior, most likely you are controlled by the flesh. And if you have accepted Jesus Christ as your Lord and Savior, you have the Holy Spirit to help you in our earthly life.
If you have questions , ask your priest, pastor, or Christian friend.
