Philemon 1:7
For I have derived much joy and comfort from your love, my brother, because the hearts of the saints have been refreshed through you — Paul's emotional response (splanchnai = bowels/heart metaphorically) to Philemon's love demonstrates the relational foundation of the letter. The saints' hearts (splanchnoi tōn hagiōn) being refreshed (anapaō) through Philemon's ministry establishes his reputation for Christian kindness. This precedent becomes Paul's basis for the forthcoming appeal: act toward Onesimus as you have toward others.
