The Law of Faith

Galatians  3:11 But that no man is justified by the law in the sight of God, it is evident: for, The just shall live by faith.  12 And the law is not of faith: but, The man that doeth them shall live in them.

Here it is seen that we are justified by faith. But we know that we are saved by grace also.

Ephesians 2:8 KJV For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:

The believer is saved by the undeserved kindness of God when we believe on Jesus and confess him with our mouth.

There is no grace for the believer that does not come through faith. That is why is a law. Too often people want to believe that grace is unlimited AND unconditional and inescapably omnipresent. No. Grace is dependent on faith, not the other way around.

Romans 4:16   Therefore it is of faith, that it might be by grace; to the end the promise might be sure to all the seed; not to that only which is of the law, but to that also which is of the faith of Abraham; who is the father of us all,

Faith is how we received grace at salvation, and faith is how we receive grace every day.
To believe we receive grace without living by faith (relationship with Jesus), we violate the Law of Faith. Rom 3:27  Where is boasting then? It is excluded. By what law? of works? Nay: but by the law of faith.
