This is how physical healing works, hope it helps, and I’ll give you a video to watch on healing.
Physical healing is part of the Atonement of Jesus, that’s why the word SOZO is translated as both SAVED and HEALED in the Bible - because the word means to be completely made whole, spiritually, emotionally and physically, NOT just spiritually.
Romans 10:13 for just one example: whosoever shall call upon the name of the Lord, shall be SOZO (saved).
SOZO: (made completely whole - spiritually, emotionally, and physically)
The Bible shows us healing is available for everyone who has been saved, because of His Atonement.
1) Healing is the children’s bread; (Matt. 15:22-28)
2) Jesus already healed us by His stripes (1 Peter 2:24).
3) Jesus healed everyone who was sick, in fulfillment of Isaiah’s prophesy that He took our infirmities and bore our sicknesses
Matthew 8:16-17, (refers to Isaiah 53:4-5, the Atonement of Jesus).
4) The benefits of God is He forgiveness ALL our sins and heals ALL our diseases Psalm 103:3;
Also, many are the afflictions of the righteous but God delivers them out of THEM ALL,
Psalm 34:19
5) Healing is such a part of His atonement that Jesus healed a paralytic by forgiving his sins: “pick up your mat and walk, your sins have been forgiven”. Luke 5:20-25
Psalm 103:3, Luke 5:20-25, and James 5:13-15 all link physical healing with forgiveness of sin.
Why? It’s part of salvation - of being made completely whole, spiritually, emotionally, and physically - SOZO - interchangeably translated in the Bible, as ‘saved’, and ‘healed’.
The Hebrew in Isaiah 53:5 means: by His wounds, bruises, and stripes, we are made completely whole.
Not partially whole, with just our sins forgiven, but made completely whole.
One of the ways to be healed is when you thank Him and praise Him that you were already healed of your sickness 2,000 years ago, by Jesus’ stripes, and thus appropriate by faith what Jesus already provided.
Kenneth Hagin came off his death bed as a teenager, by reading the Bible, and believing Mark 11:23-24, and acting on his faith.
Another way is in James5:14-16 where we are promised:
James 5:14 Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:
Jas 5:15 And the prayer of faith SHALL save (SOZO) the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him.
Jas 5:16 Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
And Jesus promised that a sign that will follow those who believe, is their laying hands on the sick, and they will recover, in Mark 16:17-18.
Here’s a video on how healing works, he’s well known, and explains how Jesus alr day healed us by His stripes, and we just have to learn how to receive by faith, what He’s already done:
