In Hebrew the Name of the Holy Spirit is the Ruach HaKodesh. I have had a lot of experience with spiritual warfare because of mostly self-imposed trauma and I can also personally testify that it makes a great difference. Obviously I believe how the song says - There is power in the name of Jesus, especially when people are ignorant of the true names and of Yah's great desire that we should use them as He often mentions in the Holy Bible - He knows our hearts and He knows when we are being sincere and calling on Him - but how greater is the power in the Name of Yahshua.
