Luke 10:18-20 "And He said to them, “I saw Satan fall like lightning from heaven.  Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you.  Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven.”"
Returning from their 'mission' trip, the 72 disciples of Jesus were filled with joy. "Even the devils are subject to us through your name", they said. Jesus responded that He saw Satan fall like lightening from Heaven and that He had given them authority to trample snakes and scorpions and to overcome all the power of the enemy.
The nature of the enemy is to fall. His destiny and his eternal condition is Fallen. Thus, Satan and his demons want to pull us down with them. Their schemes are subtle, as they watch carefully in every  to pull you down with them. But our calling and destiny is not to fall, it is to rise. Our identity and our authority as the children of God is with the resurrected Messiah. And it's His resurrection life and power that gives us authority over evil and victory over sin – to rise above temptation through a life of spirit-empowered obedience. "For He has rescued us from darkness and brought us into the kingdom of the Son."  [Colossians 1:13]
You are no longer under the power of the evil one, but in the power of a risen God. Rise above temptation. Exercise His authority in your life, and be led by His Holy Spirit. The authority of our risen Lord over evil is one of our great living testimonies to His goodness and salvation!
