To me, the New Testament verse that sums up Isaiah 53 the best is I Peter 3:18;
"For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive by the Spirit..."
It tells us that
Christ died for all sins once.
That He died, the righteous for the unrighteous.
That He brought us to God.
That His died a physical death.
That He was made alive by the Spirit.
