In first part of this section (vs.14-15) Jesus goes to Peter’s house and seeing Peter’s mother-in-law lying sick with a fever he heals her. There are a couple of interesting points here in this small section. Firstly this woman was Peter’s mother-in-law which shows that he had a wife and thus was married. This was further indicated by Paul who likewise showed that Peter was married in 1 Corinthians 9:5. Some have thought that Peter was celibate but this was clearly not the case.
The second thing we see in this small section is that Peter’s mother-in-law had a fever. Most fevers are associated with infection of some kind and usually not too much to worry about. We don’t know how serious this fever was or the underlying condition causing the fever. It may well have been associated with something quite minor such as a common cold or could have been something more serious. The point here though is that if this was a minor condition it shows that Jesus was concerned not with just major health issues, which were the “big” miracles, but he was also concerned with the small infirmities as well. God is not just God of the big stuff but of the small stuff too. And there is no problem too large or too small that we cannot take to him, even a minor fever from the common cold.
In the next verse (vs. 16) we see many people were brought to him for healing and to have demons exorcised and he healed all of these people. There were no questions, no requirements to be healed, no offerings given or requested. It was a matter as simple as, they came, they were sick and he healed them. All who came were healed. None were too difficult and no case was a bother to him.
Matthew then wrote in the final verse in this section (vs. 17) that Jesus was fulfilling the prophecy of Isaiah who said, “He took our infirmities and bore our diseases.” So we see from this and my previous posts that there were many purposes to these miracles and healings. They were a sign to confirm the message he preached, they were to fulfil Old Testament prophecies and of course they were to show the power of God.
