Preparation is important!
Preparation consist of two parts
1) Forgiveness is fundamental. You will find a suggestion of prayers on the page Prayer for forgiveness.
2) Read through the page about possible demonic problems. Ask for the guidance of the Holy Spirit and write down the things that you think you need to be delivered from.
Remember that God is where you are. He is with his children by the Holy Spirit. God is not confined to space or time.
Finally
Listen to the sound track – and participate with a loud and clear voice.
God bless you!
