Philemon 1:6
And I pray that the sharing of your faith may become effective by the knowledge of all the good that is being done through us for Christ — the petition (deomai) asks that Philemon's faith-sharing (koinōnia tēs pisteōs) become energetic (energēs) through experiential knowledge (epignōsis) of the good accomplished in Christian community. The phrase good being done through us hints at the forthcoming request — that Philemon participate in the gospel's redemptive work through his treatment of Onesimus. Faith becomes concrete and powerful through costly action.
