'Once for All' in the Bible

Do not offer any part of your bodies to Sin, in the cause of unrighteousness, but once for all offer yourselves to God (as those who, though once dead, now have Life), and devote every part of your bodies to the cause of righteousness.

For if those who were once for all brought into the Light, and learned to appreciate the gift from Heaven, and came to share in the Holy Spirit,

For Christ himself died to atone for sins once for all--the good on behalf of the bad--that he might bring you to God; his body being put to death, but his spirit entering upon new Life.

Dear friends, while I was making every effort to write to you about our common Salvation, I felt that I must write to you at once to urge you to fight in defense of the Faith that has once for all been entrusted to the keeping of Christ's People.
