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

But he was wounded because of our crimes, crushed because of our sins; the disciplining that makes us whole fell on him, and by his bruises we are healed.

For he himself is our shalom — he has made us both one and has broken down the m’chitzah which divided us

by destroying in his own body the enmity occasioned by the Torah, with its commands set forth in the form of ordinances. He did this in order to create in union with himself from the two groups a single new humanity and thus make shalom,

and through his Son to reconcile to himself all things, whether on earth or in heaven, making peace through him, through having his Son shed his blood by being executed on a stake.
