Comfort or Call to Action?

The last two posts have mentioned the comfort (and confidence) given to believers by the promises in verses like Romans 8 : 28.

And we know that for those who love God all things work together for good, for those who are called according to his purpose.
[ESV]

Interestingly, the sentence structure of this verse in the Greek is not really clear.
The above ESV translation, and many others, translate on the assumption that "all things" is the subject of the sentence, so that the "all things" are what work for good for those who love the Lord.

However, it is quite possible that "God" is the subject of this sentence, so that it is God who does the work.
The NIV nudges itself in that direction with:

And we know that in all things God works for the good of those who love him, who have been called according to his purpose.
[NIV]

It is also possible that it is God and those who love Him is the subject and therefore are those who are working together for good.
The NIV offers this alternative in a footnote:

that in all things God works together with those who love him to bring about what is good—with those who have been called according to his purpose.

The Good News Bible and the Revised Standard Version offer this construction in the body of their translations.

We know that in all things God works for good with those who love him, those whom he has called according to his purpose.
[GNB]
We know that in everything God works for good with those who love him, who are called according to his purpose.
[RSV]

So although our comforting version (where God works all things for our good) is by far the most popular English translation, it is possible that this verse is also calling us to work with God to achieve the good He has planned.

Which fits nicely with:

For we are God’s handiwork, created in Christ Jesus to do good works, which God prepared in advance for us to do.
[Ephesians 2 : 10  NIV]

The question: Comfort or Call to Action?
I say: BOTH.

It's good to know that God has everything in hand for my good 

AND 

providing I am doing what God has called me to do, He will be working with me to see it achieved.
