In 1994 in the province of Quebec in Canada I experienced what is called the conviction of sin it was a supernatural experience and this took place after my mother had prayed for me for 16 years, I saw things I would have never thought possible I experienced things I never thought I would experience life-changing experience and later on I found out it was called the new birth that Jesus talked about and the Gospel of John chapter 3 the need to be born again to see the kingdom of God which is exactly what happened to me and to some degree yes on that very day I died, I died to self, I began to die to the old man, I began to die to the things of this world, I began to die to carnal thinking to wrong thinking and believing, and this is available to every whosoever out there because I was one of them prior to that experience since we're all born atheists having been an Atheist for 31 years before the New Birth experience., my sister went Home 13 years ago and then my father 9 years ago and my Mama who I loved so much and was her caregiver until she went Home also at the age of 96 I will get to see them all over again and be with them for eternity which is part of the good news.

when it comes to Healing or even Salvation or Provision these three great Positional Truths are things you never ask for because they are things that have already been done and  given to us freely  yet positionally because of the Cross and back in the garden before the Fall of Man., meaning they have to be received by believing. Begin Renewing Your Mind with healing verses and provision verses meditating upon them as much as possible everyday sowing those verses as seeds in order to have a harvest Luke 8:11. To answer the other part of your question at this time is too time-consuming. I learned years ago the hard way to assimilate whole chapters and even whole Epistles to get the proper interpretation from the Holy Spirit in order to avoid false teachings and false doctrines since I'm an Apostolic International missionary, I did not want to teach false Doctrine like many preachers in Bible teachers do by taking  verses out of their proper context but getting His Mind regarding His Word.

 Once you are Born Again, if you don't tell your heart what to believe, the devil will do it for you

 When it comes to Healing actually it's not a promise because it's something that's already been done yet positionally at the cross.Promises are not something that we're done at the cross. The three greatest position of truths that were done for mankind of the cross with salvation, healing and provision

 we let Satan rule the world and not God because God gave Dominion to man, God told man to guard the garden to protect the garden from the serpent into this very day we the church the new creation the body of Christ are the guardians of the truth the pillar and foundation of the truth

 To believe in religion is a hard pass, but to believe in Jesus, wholeheartedly yes.

 God in his foreknowledge has elected and predestined and ordained every human being to be saved and he did save them all at the cross yet positionally, meaning they have to receive what he's already done for them positionally at the cross by believing.
