if that is true in post cross times alot of what christ taught his disiples is false and why would he bother and can he be wrong?
we need to interpret scripture in light of what happened at the cross. we are not saying that Jesus taught his disciples false things. certainly not. but the Bible does say Jesus was born under law, and had to 'obey' the laws too. but we the church are no longer under law.
In the original greek
1 Peter 2:24 reads
"Who the sins of us himself carried up in the body of him onto the tree inorder that to sins dying to righteousness we might live of whom by the bruise ye were cured."
I will quote from my article:
Healing and health
The literal truth about Isaiah 53:3-5
Besides our sins, Jesus also bore our sicknesses and pains on the cross. He was also whipped 39 times on His back (till His flesh was torn and His bones exposed) to buy us healing.
* Isaiah 53:4,5
4 Surely he hath borne our griefs [sicknesses], and carried our sorrows [pains]: yet we did esteem him stricken, smitten of God, and afflicted.
5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
The original Hebrew words for "griefs" and "sorrows" are actually "sicknesses" and "pains" (physical and mental) respectively (see Strong's numbers 02483 and 04341). The translation is thus unfortunate. You can check with Young's Literal Translation too, or ask any Christian Jew what his Hebrew Bible says.
Some have insisted that Isaiah 53:4 has to do with spiritual healing only. But let the Bible interpret the Bible. The verses are quoted again in Matthew 8:17 and 1 Peter 2:24. How does the Holy Spirit translate Isaiah 53:4 in Matthew 8:15? He says, "Himself took our infirmities, and bare our sicknesses", implying physical healing.
* Matthew 8:15-17
15 And he touched her hand, and the fever left her: and she arose, and ministered unto them.
16 When the even was come, they brought unto him many that were possessed with devils: and he cast out the spirits with his word, and healed all that were sick:
17 That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses.
Moreover, the immediate context of Matthew 8:17 (verses 15 and 16) proves that the verse is referring to physical healing. This is not to say that spiritual healing is excluded as demons were cast out too.
Note also that the word "Surely" is used in Isaiah 53:4. It is as though God knew that Christians would not have difficulty believing that Jesus bore their sins, but would find it hard to believe that Jesus also bore their sicknesses and pains, hence, He added the word "Surely"! You don't find that "double assurance" in verse 5, which talks about Christ bearing and suffering for our sins.
The verse before Isaiah 53:4 says:
* Isaiah 53:3
3 He is despised and rejected of men; a man of sorrows [pains], and acquainted with grief [sicknesses]: and we hid as it were our faces from him; he was despised, and we esteemed him not.
Again, the original Hebrew words for "griefs" and "sorrows" are "sicknesses" and "pains" (physical and mental). The translation here is also inaccurate.
As with verse 4, verse 3 is talking about Jesus' suffering on the cross -- He became a man of pains and sicknesses because He was carrying all our physical and mental pains, as well as all our diseases. In fact, His face and body were so disfigured by the pains and diseases that those who saw Him were appalled and hid their faces from Him (verse 3).
* Isaiah 52:14
14 As many were astonied at thee; his visage was so marred more than any man, and his form more than the sons of men:
In Isaiah 53:5, it says:
* Isaiah 53:5
5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
The Hebrew word for "peace" here is "shalom" (see Strong's number 07965). It is a very rich word and means completeness (in number); safety, soundness (in body); welfare, health, prosperity; peace, quiet, tranquillity, contentment; peace, friendship (of human relationships and with God especially in covenant relationship); peace (from war) and peace (as an adjective).
Jesus was punished in our place so that we could have "shalom", which includes health and prosperity!
Now, Isaiah and Paul both asked, "Who hath believed our report?" In other words, can we believe this wonderful aspect of the gospel -- that Christ also bore our sicknesses and pains, besides our sins?
* Isaiah 53:1
1 Who hath believed our report? and to whom is the arm of the LORD revealed?
* Romans 10:16
16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report?
If Christians would believe and receive this report gladly, then "the arm of the LORD" -- His miraculous powers -- will be revealed to them.
There is a lot more to say, but I'm lazy to cut and paste so pls if you have time, read about the bronze serpent & redeemed from every type of sickness here:
