The Chastisement of our Peace

Isaiah 53:5 KJV
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.
Learned something for the first time at prayer meeting Thursday... As many times as I have read this verse, I never pondered the significance of the chastisement of our peace being upon Jesus. Sure, he shed his blood for our sins, and his body was beaten so that we could have physical healing, but what does it mean when it says the chastisement of our peace was upon him?
He not only died so that we could be redeemed, and so that we could have healing, but also so that we could have peace... not only peace with God, but peace of mind! He rebuked that which kept us from being at peace. In the Hebrew this word peace has many different meanings which I will list here:

1) completeness, soundness, welfare, peace

a) completeness (in number)

b) safety, soundness (in body)

c) welfare, health, prosperity

d) peace, quiet, tranquillity, contentment

e) peace, friendship

1) of human relationships

2) with God especially in covenant relationship

f) peace (from war)

g) peace (as adjective)

It is interesting to me that completeness and soundness are the first two definitions listed. After we are saved we are given the mind of Christ! We are given the keys to freedom from the prison of anxieties, worries, stress, and all mental disorders! He has completed us in Christ and given us a sound mind! I wish I'd realized all this back when I was in therapy! I've always thought of peace in other aspects such as our restored relationship with the Father, our ability to get along with others, and the millennial kingdom when Jesus sits on the throne and the lion and the lamb lie together. Funny, I have talked of wanting some peace of mind, and even talked about renewing my mind in the Word... but never stopped to think that all of that is part of Christ's finished work on the cross! Maybe I'm the only one, but I thought I'd share that. I never connected those dots! How are we to be given the mind of Christ, how are we to have that sound mind absent of fear, how can we possibly renew our minds in the Word of God if Christ had not made a way for it?? All gifts that the Father gives are a result of the Son's death, burial and resurrection! WOW! Just gives me renewed faith to be healed of all this depression and mood swing junk I've dealt with for so long.
