John 1:30

This is he of whom I said, After me cometh a man who is become before me: for he was before me.

Every line of the fourth Gospel is directed to establishing the identity of Christ as God incarnated, or God come in the flesh; and this verse can be true only in that context. John the Baptist was older than Christ, having been conceived six months earlier (Luke 1:36), and it could be true that Christ was "before" John the Baptist only with respect to his eternal existence, a truth John had already recorded in John 1:15.
