The point that I was making is that a lot of people try to make satan coequal with G-d, and that is a falsehood. Satan only does what G-d allows him to do. He was created as the deceiver, which is what he does. Any power that satan has is given to him by the people that fall under his deception. We are given clear choices between good and evil, but G-d gives us the power to overcome evil. Therefore, it is not a battle against satan, but a sprint towards the G-d of the universe.
The only way a person has the power to overcome evil is if he has accepted Christ as Savior and has the indwelling of the Holy Spirit to equip him with the strength to overcome evil. A person who is unsaved, who does not know Christ as Savior, is a slave to sin and is in bondage to sin and is not only helpless to overcome sin but can never have the hope of meeting God's standards for righteousness and being acceptable to God on his own, without the covering of the shed blood of Jesus Christ.
So, as the Bible says, the enemy of God and all those who know Him and have a personal relationship with Him is indeed Satan, aka the "god of this age" as the Holy Spirit refers to him.
