This may be. Paul had some ability to offer grace as an apostle. I see no indication of this in the Word, nor would it make sense, since grace extends from God. Actually the term thee is plural, so Paul is most likely addressing the other elders or leaders if not the entire church at Ephesus. This might assist us in determining the meaning.
Grace is an item that is needed in any church.
We need to treat one another as if we realize we are all products of grace. We need to treat our leaders as if we hold them in favor. Leaders need to treat the congregation as if they hold them in favor. We all need to be gracious to one another at all times. There needs to be a mutual respect by all.
