Those who were sent to the house where the sick servant had been found him completely healed. The evidence of the servant's healing was abundant, excellent, and very visible; they did not need to look through a microscope to prove that he was healed. He had been paralyzed, in great pain, and near death, but now he was completely well. They needed no other proof to convince them that a genuine miracle had occurred.
Jesus provided many infallible proofs during his ministry that confirm his supernatural ability and divine purpose (Acts 1:3). The world makes every effort to discredit God the Father and Jesus Christ and their miraculous works, when the proof of their sovereignty and power are seen in everyday things. "For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse" (Romans 1:20-21, ESV). Do we see God at work in our lives?
