Galatians 6:15-16

For neither is circumcision anything [of any importance], nor uncircumcision, but [only] a new creation [which is the result of a new birth—a spiritual transformation—a new nature in Christ Jesus]. Peace and mercy be upon all who walk by this rule [who discipline themselves and conduct their lives by this principle], and upon the [true] Israel of God (Jewish believers). [Ps 125:5]
