There is no partiality with God. Romans 1.
That's not in Romans 1. It's in Romans 2:11 and the context is about how all will be judged. It is about those who do good to be accepted by God (which is proven an impossibility in chapter 3) or those who do evil (that's the entire world.)
Paul proves that none can do good to be accepted by God in Romans 3, that all are under condemnation, all have sinned, 3:23 and under this condemnation there is no distinction; 3:22 -- all are in the same boat, the whole world is guilty before God; 3:19.
You're in the wrong chapter and out of context. It doesn't refute the fact that God elects whom he wills, grants faith to whom he wills according to his purpose, counsel and will, and passes over others, not extending them mercy, Romans 9:16-20. Thherefore the verse you've alluded to you've misused and misapplied, and had the wrong chapter altogether.
And that isn't favoritism, it isn't showing partiality, it's called grace, of which God is entitled to grant to whomsoever he wills, or it isn't grace at all since he grants it based on nothing good in them, it is all according to his will to do so. 1 Corinthians 1:26-31.
