Power went out from Jesus!
Today much surgery is being done with the help of LASER’S (Light amplified by stimulated emission of Radiation), through keyhole surgery with tremendous success and cures for cancers of various types and the whole field is being improved on a daily bases with Oncology?
But Jesus was the first to deliver a power emitted from his body to heal the many who made their way to Him! Jesus knew what power was coming out from Him, since He was admitting it, but in the case of the woman suffering twelve years of misdiagnosed bleeding He made it an issue to show His love, mercy and restoration of this poor lady!
Mark 5:3, Luke 6:19, 8:45-46.
Ask me and I will tell you!
