But I did not want to do anything without your permission, so that your goodness [of heart] would not be shown out of a feeling of obligation, but out of willingness.

If then you consider me to be a partner [in the faith], welcome him [back] as [you would] me.

So, brother, I would like to have your help in [the fellowship of] the Lord; cheer me up in Christ [i.e., by welcoming Onesimus back on good terms].
