Here is yet another perspective.
Mat 16:19 and I will give to thee the keys of the reign of the heavens, and whatever thou may bind upon the earth shall be having been bound in the heavens, and whatever thou may loose upon the earth shall be having been loosed in the heavens.' (YLT)
Now compare that with what is said in John chapter 20.
John 20:21 Jesus, therefore, said to them again, `Peace to you; according as the Father hath sent Me, I also send you;'
v. 22 and this having said, He breathed on them, and saith to them, `Receive the Holy Spirit;
v. 23 if of any ye may loose the sins, they are loosed to them; if of any ye may retain (the sins), they (the sins) have been retained.' (YLT)
"According as the Father sent Christ" to forgive/remit sins... likewise "I also send you" (also John 17:18). I believe it is the 'sins' which they were instructed to forgive in this passage. So could Jesus have been speaking of healing in that verse?
Mark 2:9 Which is easier, to say to the paralytic, "Your sins are forgiven you,' or to say, "Arise, take up your bed and walk'?
v. 10 But that you may know that the Son of Man has power on earth to forgive sins"--He said to the paralytic,
v. 11 "I say to you, arise, take up your bed, and go to your house."
Was Jesus saying here that healing is forgiving sin? And Jesus did command them to "heal the sick."
Luke 10:8 Whatever city you enter, and they receive you, eat such things as are set before you.
v. 9 And heal the sick there, and say to them, "The kingdom of God has come near to you.'
We know that the Apostles did heal many people during their ministry.
Acts 5:15 so that they brought the sick out into the streets and laid them on beds and couches, that at least the shadow of Peter passing by might fall on some of them.
v. 16 Also a multitude gathered from the surrounding cities to Jerusalem, bringing sick people and those who were tormented by unclean spirits, and they were all healed.
Acts 28:8 And it happened that the father of Publius lay sick of a fever and dysentery. Paul went in to him and prayed, and he laid his hands on him and healed him.
v. 9 So when this was done, the rest of those on the island who had diseases also came and were healed.
Mark 11:24 Therefore I say to you, All things, whatever you ask, praying, believe that you shall receive them, and it will be to you.
v. 25 And when you stand praying, if you have anything against anyone, forgive it so that also your Father in Heaven may forgive you your trespasses.
v. 26 But if you do not forgive, neither will your Father in Heaven forgive your trespasses.
mercy, peace and love
