And these things write we unto you, that your joy may be full.
And we are now writing these things to you so that our joy [in seeing you included] may be full [and your joy may be complete].

We are writing these things so that our joy can be complete.
And this we write to you, so that you may rejoice, and so that your joy may be full.
