The difference is just one of control and POWER.
With a magic incantation the person or the power they are operating under controls the content, direction and transmission.
With praying in tongues My Spirit formulates and decrees and you just use your voice.
As to the power source – you can tell if it’s me by the peace you will feel.
Yes but remember I’m bigger and stronger and have broken all hold of evil and death through my new covenant in blood. Remember battles can be won long before you see the victory or before the victory is out-worked.
