text: Every single person that Jesus healed eventually died.
  Does this mean Jesus's healing acts weren't perfect? No 
  They were perfect in the sense that they were complete and in the sense that they were perfectly in line with the will of God.   They weren't perfect in the sense of "power", the power to infinitely keep illness out of a person.  Could God have rendered infinite healing into these people?  Of course.  But it wasn't His will.
  
  Prayer is really an act of "union" with God, through conversation.
  There are other forms and acts of "union", such as an act of pure charity (an act of pure charity is done solely for the love of God, not for accolades, not for better friendship with the person that one is helping, etc.)
  
  The most important thing for our soul that we can do on earth is draw closer to God.  So prayer is infinitely more effective when it helps our soul, or the soul of others, than when it leads to a physical miracle, because the soul is that important compared to the body.
