“We know that all things work together for good for those who love God, for those who are called according to his purpose.”
Paul says what the good is two verses later, and it is not that things turn out nicely.
What it means
“Work together” renders a compound verb — things woven with each other toward an end. Paul is not claiming each individual thing is good. He is claiming none of them is wasted.
The named good is likeness to Christ. That is a real promise and a costly one, and it explains how the sentence can sit in a chapter that has just described groaning without pretending the groaning is pleasant.
What it does not mean
It is not “everything happens for a reason.” That sentence assigns a purpose to the loss itself; Paul assigns a purpose to God’s weaving, which is a different claim.
It is not something to say to someone at a graveside. Romans 8 refuses to call the bad thing good — which is precisely why the verse is trustworthy once the noise dies down.
Where it sits
Romans 8 is a chapter about suffering. By verse 18 Paul has weighed present suffering against future glory; by verse 22 he has creation groaning; by verse 26 the Spirit is praying on our behalf because we do not know how.
Verse 28 is the conclusion of that argument, not a standalone consolation. And verse 29 supplies the definition: the good is being conformed to the image of his Son.

God, I cannot see how this fits and I am not going to pretend it was good. Weave it anyway. Make something of me through it that could not have been made another way, and do not let it be wasted. Amen.
