The Bible sometimes uses the same words (sign, wonders, power) used to describe the miracles of God and the power of satan.

Revelation 16:14 (NKJV)

For they are spirits of demons, performing signs, which go out to the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.

2 Thessalonians 2:9 (NKJV)

The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders,

So do they have the same powers? No, they do not. The devil is a created being and, therefore, only has limited power. Although Satan has great spiritual powers, there is a vast difference between the devil’s power and God’s.

In conclusion, all the power that the devil has is given to him by God and is carefully limited and monitored. But what truly matters is that Christ has defeated the devil and has triumphed over him and over all his followers:

Colossians 2:15 (NKJV)

Having disarmed principalities and powers, He made a public spectacle of them, triumphing over them in it.

In doing so Christ has giving power to His people to be victorious over demonic forces. Thus, John informed believers:

1 John 4:4 (NKJV)

You are of God, little children, and have overcome them, because He who is in you is greater than he who is in the world.
