John 4:48 (NKJV) 48 Then Jesus said to him, "Unless you people see signs and wonders, you will by no means believe."
There is an interesting story in John 4:46-54. There was a royal official whose son had become ill to the point of death. In this story the Word of God demonstrates to us an increase in faith and how we can achieve it.
The man was requesting that Jesus would come and heal his son. Jesus responded with the above quote which at first read might seem a little bit unusual. Jesus said, "unless you see signs you will not believe". Then Jesus went on to say in John 4:50, "...Go your way; your son lives." Then the passage tells us that the man believed the word that Jesus spoke to him, and he went his way.
Now it was at least a 2 day journey to the mans home. The next day on his way home his servants came to meet him. They came to tell him that his son was getting better and the fever broke. The man asked the servant at what time did the fever leave? The man determined that it was at the exact time that Jesus declared "Go your way; your son lives."
This is what happened next. John 4:53 says, "So the father knew that it was at the same hour in which Jesus said to him, "Your son lives." And he himself believed, and his whole household.
Since we know that the man already believed (V.50) this had to be an increase of belief. In fact faith increased so much that he and his whole household believed!
The boys fever had broken but he wasn't completely healed yet. I can assure you that this young man received a complete recovery. If you are believing for something right now look for God in the situation just as this man did. It will take you to a new level of faith and you will see your victory.
So multiply your faith and be blessed!
