Translation Question: Philemon 1:5

This questions comes following a post I did here. My question comes from the second paragraph where I talk about verse 5. Basically, is the NIV justified in rendering the verse “because I hear about your faith in the Lord Jesus and your love for all the saints.”  The underlying Greek is this: ἀκούων σου τὴν ἀγάπην καὶ τὴν πίστιν ἣν ἔχεις πρὸς τὸν κύριονἸησοῦν καὶ εἰς πάντας τοὺς ἁγίους. A rather literal translation would be, “I hear about your love and faith(fulness) that you have toward the Lord Jesus and toward all the saints.” The basis for translating according to the (T)NIV, as I understand it, is something called chiastic structure. Basically, it’s a literary structure where the pairs go A B B A. If that’s the structure Paul has in mind, then the majority of modern translations are justified in going with pairing faith with Jesus and pairing love with saints. If πιστις is rendered as faith, then I understand how the chiastic structure is necessary. If we go with a broader meaning for πιστις, like faithfulness or loyalty, then it would be perfectly fine to have both πιστις and αγαπη applying to both Jesus and the saints. What is the full justification for rendering it like the NIV? I’ve only seen the chiastic structure assumed, not argued. Are we harmonizing with Colossians 1? Input from more knowledgeable in Greek would be wonderful. :-)
