How did HE know?

I don't mean to sound religious, but I am a Christan, which I will never deny.  Yesterday I was driving by a church in my local town.  This church was in the middle of the desert.  I had been wanting someone to pray over me because I felt a negative spiritual attack was happening to me.  It just so happen that this church was having a special Saturday night service.  After hearing the message which was a special book in the bible for me, the pastor giving the message asked if anyone needed prayer so I went forward. The pastor just laid hands on me and prayed about this attack that was against me... how did he know?  The Holy Spirit is everywhere and knows all things.  I pray the blood Jesus all the time, but sometimes like the bible says, we need others to help us.  Today is a much better day.
