I found the section of scripture that uses the term grace related to collecting and delivering money from Macedonian and Greek saints to suffering Jerusalem saints:

I also put the word grace into the search window of Bible Hub and a treasure trove of great old and New Testament verses came up.
Enjoying God’s grace to us is fantastic, but perhaps there is an objective standard in these verses: enjoying God’s grace to us in Christ should result in compassion and giving toward our fellow believers, “glory towards the Lord”, and “taking great care to do what is right, not only before the Lord, but also before men.”
