What does John 1:14 reveal about who God the Father is?
Nothing explicit is said about God the Father. We know that the Father is the one who sent the Son to make him known (John 1:14b). The Father is thus one who reveals himself, he does not remain hidden.
14 Et la Parole a été faite chair, et elle a habité parmi nous, pleine de grâce et de vérité; et nous avons contemplé sa gloire, une gloire comme la gloire du Fils unique venu du Père.
