Here is something simple, but GREAT.
One of our youth had a boil in a very bad place, his bum. It was swolen and very painful, he had had it for 3 days.
He attended a youth prayer meeting where the Holy Spirit moves in power.
With no one praying for him, the boil burst and all the puss started coming out of the boil, then He was instantly and completely healed, no pain, no problem, no nothing…just his miracle.
It sounds so simple, because it is so simple. The Holy Spirit is POWER.
