There is an “Obedience” Factor to Faith - Romans 1-2

Romans 1:5 (ESV Strong's)
... through whom we have received grace and apostleship to bring about the obedience of faith for the sake of his name among all the nations,

There is an “Obedience” Factor to Faith

Paul starts out the book of Romans outlining his purpose.  That outline culminates with the above verse.   He, Paul, received his apostles in for the purpose of bringing about “the obedience of faith.”   This is how he STARTS the long book of Romans.  But, unlike many authors today, Paul does not lose his focus.   After fifteen chapters, note how he ends the book:

Romans 16:25-27 (ESV Strong's)
Now to him who is able to strengthen you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery that was kept secret for long ages but has now been disclosed and through the prophetic writings has been made known to all nations, according to the command of the eternal God, to bring about the obedience of faith— to the only wise God be glory forevermore through Jesus Christ! Amen.

In Paul’s doxology to the book, he also speaks and states the purpose:  “To bring about the obedience of faith ...”.    

Faith is putting all your assurance in something.   In this case we are putting all our trust and assurance in the fact that Christ died for our sins.   That is the focus of our faith.  But, our faith also has a component of obedience as we trust the promises and precepts of His word and “obey” them.   We can’t have “faith” without “obedience.”   There is no such things as faith without obedience.    Having faith in God means we trust Him and will do as He tell us to do in life.    The obedience is the evidence of our faith.  But, the “Power” behind the obedience is also God’s work.   We simply trust that He will give us the power to walk in faithful obedience to our faith.    Paul said it this way to the church at Corinth:

1 Corinthians 15:10 (ESV Strong's)
But by the grace of God I am what I am, and his grace toward me was not in vain. On the contrary, I worked harder than any of them, though it was not I, but the grace of God that is with me.

Faithful obedience is the norm for the believer.  Anything else is just fake.
