In The gospel of John chapter 5- Jesus comes in and skips over other cripple, other sick, and other hurting people, in fact he skips over everybody else who has an issue except this one man and chooses him to heal.
I believe that the reason Jesus stopped by to HBO ( help this brother out) has something to do with the fact that he respected the fact that this brother kept showing up.
For 38 years this brother kept showing up. ( Respect my brother)
Despite the fact that His confidence and his faith had been tested for 38 years, yet here he is at the pool of Bethesda again still hoping, still believing and still showing up.
