Angels are “activated” by the Word of God spoken by believers. If you remember the Super Friends Wonder Twins, they had hidden power but they didn’t manifest until they said, “Wonder Twin Powers Activate!” Likewise angels are activated by the “voice of God’s Word” spoken by believers. They’re always there, waiting for a prayer or scriptural declaration for activation. They are mighty and sent to serve the heirs of salvation. But they will only serve according to God’s will. So when we pray and declare God’s Word we can know that we’ve been heard and that angels are activated and providing supernatural assistance.
On the other hand the enemy and his host are fallen angels. They come to “kill, steal and destroy” and are activated by words of destruction. If you choose to speak evil of yourself then they are there to activate it. They work with wicked words to twist and destroy.
Your mouth is a door to the realm of the supernatural, when you speak the blessing of the Word you open it up to the “Super Friends” and when you speak the words of the world’s curse and open it to up the “Legion of Doom.”
Ps 103:20-21
20 Bless the Lord, you His angels,
Who excel in strength, who do His word,
Heeding the voice of His word.
21 Bless the Lord, all you His hosts,
You ministers of His, who do His pleasure.
