God chooses who He will and will not heal according to HIS will, not yours...
The Lord Jesus, while upon earth, demonstrated that God's will is to heal, and to heal
ALL who come to Him for healing!
There is
NOT one instance when a person came to Jesus seeking healing that they did
NOT receive it!
The reason why divine healing is not widely available through the Body of Christ today is simply because of unbelief and prayerlessness!
James 5v14-18 "Is anyone among you sick? Let him call for the elders of the church (it is
YOUR responsibility to call for the Pastor/Elder), and let them pray over him, anointing him with oil in the name of the Lord. And the prayer of faith (this is the Pastor's/Elder's faith
NOT yours) will save the sick, and the Lord will raise him up. And if he has committed sins, he will be forgiven. Confess your trespasses to one another, and pray for one another, that you may be healed. The effective, fervent prayer of a righteous man avails much. Elijah was a man with a nature like ours, and he prayed earnestly (this is also the Pastor's/Elder's responsibility) that it would not rain; and it did not rain on the land for three years and six months. And he prayed again, and the heaven gave rain, and the earth produced its fruit."
Basically this is the operation of the "gifts of healings" as listed in 1Cor 12v7-11.
There are different promises in the Scriptures for physical, mental, emotional spiritual healing.
Isaiah 53v4 states: "Surely He has borne our griefs (sicknesses, weaknesses, and distresses) and carried our sorrows and pains [of punishment], yet we [ignorantly] considered Him stricken, smitten, and afflicted by God [as if with leprosy]." [AMP] (with Matt 8v16,17)
This wonderful promise shows us that there is not only forgiveness of sin in Christ's atonement, but also
FULL healing for spirit, soul and body!
Other promises can be found in Exodus 15v26 (a covenant Name of Yahweh), 23v25, Psalm 23v3, 103v3 and so forth!
