'Principle' in the Bible

but knowing that a man is not justified on the principle of works of law nor but by the faith of Jesus Christ, we also have believed on Christ Jesus, that we might be justified on the principle of the faith of Christ; and not of works of law; because on the principle of works of law no flesh shall be justified.

This only I wish to learn of you, Have ye received the Spirit on the principle of works of law, or of the report of faith?

He therefore who ministers to you the Spirit, and works miracles among you, is it on the principle of works of law, or of the report of faith?

Know then that they that are on the principle of faith, these are Abraham's sons;

and the scripture, foreseeing that God would justify the nations on the principle of faith, announced beforehand the glad tidings to Abraham: In thee all the nations shall be blessed.

So that they who are on the principle of faith are blessed with believing Abraham.

For as many as are on the principle of works of law are under curse. For it is written, Cursed is every one who does not continue in all things which are written in the book of the law to do them;

but that by law no one is justified with God is evident, because The just shall live on the principle of faith;

but the law is not on the principle of faith; but, He that shall have done these things shall live by them.

For if the inheritance be on the principle of law, it is no longer on the principle of promise; but God gave it in grace to Abraham by promise.

Is then the law against the promises of God? Far be the thought. For if a law had been given able to quicken, then indeed righteousness were on the principle of law;

but the scripture has shut up all things under sin, that the promise, on the principle of faith of Jesus Christ, should be given to those that believe.

So that the law has been our tutor up to Christ, that we might be justified on the principle of faith.

For we, by the Spirit, on the principle of faith, await the hope of righteousness.
