Why do you feel that you must be a part of the some, that don't get healed? Does not this belief reflect upon one's heart? If I believe in God's healing, I very well may believe it for others but what about for myself? If you are confessing with your mouth that you are a part of the some that don't get healed, and thats what you've accepted in your heart, how is it that you profess faith for healing?
That may sound direct, but its the same case as with Depleted. Except she just outright said it, about whether she'll be healed in this life time or not. Her words? "Nope." You, however, are not so blunt as to just admit that you've lost hope. I am choosing my words carefully because I don't wish to offend, I am trying my best to be gentle because this topic is one that is sensitive.
In the past you and I have gone done this road, and discussed this. The difference between hope and faith. If you've accepted your, alleged, fate of not being healed in this life and then profess to all that God doesn't heal everyone, why would you so rip hope out of others? What message are you portraying of God, and what hope have you blown out? If God doesn't heal all and this is what you confess, to the person seeking healing they then have no assurance. They only have hope and we've discussed this. While hope is at times sufficient, faith is what is proficient (to get results).
You feel that there is no promise of healing, that it is something that is dependent upon God's present mercy as opposed to His established will. I cannot agree with this, except to say that God does have His timing and purposes. I believe healing, just like salvation, is available to all. There can be many factors involved here, reasons as to why a person isn't healed. Whether its their fault or not, the correct position is to have compassion. To be meek.
My question to you is, have you lost hope? Do you think God will heal you in this life time? If your answer is no, I must ask another question. Where is your faith? I say this in love, honestly. Don't lose hope. God is faithful and good. Persevere.
