In ritual, it's always best when words and action reinforce one another.
Here's one of my favorite libation formulas: quick, no nonsense, easy. In English and her sister languages, to refer to someone as "my + (name)" is a gesture of affectionate intimacy.
Drink this (name of libation) with me,
my (name of deity),
and I will drink with You.
(Pour libation.)
(Drink.)
