Our Spiritual Authority
When God created Adam and Eve, he told them to subdue the earth and rule over every creature in the sea, in the air and on the ground (Gen 1:28). Basically, they had authority over the physical earth and everything on it. When they listened to Satan the serpent and chose to disobey God, however, they abdicated to the serpent, over whom they had authority. As a result, Satan gained their authority and became the prince of this world (Jn 12:31; 14:30; 16:11); until Jesus’ crucifixion, that is.
Early in Jesus’ ministry, he gave his disciples “power and authority to drive out all demons and to cure diseases, and he sent them out to preach the kingdom of God and to heal the sick” (Lk 9:1-2). He also gave them “authority to trample on snakes and scorpions, and to overcome all the power of the enemy, so that nothing would harm” them (Lk 10:19). These statements also apply to Christians today. In both of these verses, power (dynamis) is the strength or ability to do something and authority (exousia) is the right to exercise power.
It’s significant that Jesus gave them — and us — authority over the enemy’s power, even before he defeated Satan at Calvary. He didn’t just give them — and us — more power than the enemy has so we can overpower him. Instead, Jesus gave us authority, which always prevails over power. It doesn’t matter how mean, stubborn, frightening or intimidating an evil spiritual being seems to us, our spiritual authority is what matters.
All we need to do is speak in the authority Jesus gave us. We don’t need to shout, jump up and down, threaten or foam at the mouth; simply acknowledge the authority Jesus gave us, speak the desired result and expect it to happen. It’s not up to us to produce the results; only to speak in and with authority.
By the way, after Jesus rose from the dead, he met with his disciples and announced he had received all authority in heaven and on earth (Mt 28:18). That means Satan now has no authority on earth; none, zero. Jesus is now head over every power and authority because he disarmed all powers and authorities by the cross (Col 2:10, 15). He delegated authority to us and we can expect it to be effective against any evil spiritual forces or beings.
