Bible Verses About Spiritual Peace: Is through the atonement of Christ

But He was pierced for our transgressions, He was crushed for our iniquities; the punishment that brought us peace was upon Him, and by His stripes we are healed.

For He Himself is our peace, who has made the two one and has torn down the dividing wall of hostility

by abolishing in His flesh the law of commandments and decrees. He did this to create in Himself one new man out of the two, thus making peace

and through Him to reconcile to Himself all things, whether things on earth or things in heaven, by making peace through the blood of His cross.
