So, being affectionately desirous of you, we were ready to share with you not only the gospel of God but also our own selves, because you had become very dear to us. (1 Thessalonians 2:8 - ESV)
Paul now points out that he has not stopped short at sharing with them the good news: the Gospel. He, along with Timothy and Silas, have shared themselves. This can be a challenge for those in ministry, but we ought to look to the forefathers of our faith. Ministry is not to be done at an emotional distance. It ought to be done with a nearness of heart that feels like a sharing of one's own self. Paul also shares the reason for this: they are very dear to him.
