You are describing Faith Alone Regeneration Theology which you are part of, as well as Calvin.No, it's not, it's whom we must obey. People take too many Scriptures twisted out of context and make their own religion out of it. Calvin was a whiz at it.
This theology takes scriptural generalities and indefinite statements and labels them as all encompassing affirmations.
They will then use this twisted understanding and attempt to negate or ignore the rest of the Bible.
There is a reason for James 2:24 to exist.
This is also the reason the verbiage of your "proof-text" omits any words such as "alone or only".
It is you who is inserting these concepts into the scriptures.
Can you not see this?
