Truth
Many recognize the implication that when Jesus proclaimed, "I am the Way, the Truth, and the Life," He was making a claim of deity. "The way" contains ambiguity: being the only way to something doesn't make one God. But calling oneself The Truth Itself and (Eternal) Life Itself is not the claim of a sane person.
Even more notably, both The Father and The Son are called "The True One" in parallel to each other at the end of 1 John, and that passage ends with Jesus being called "The True God." This is only the most explicit refutation of some who misconstrue John 17:3 to mean that only The Father is "the only true God." Rather, The Father and The Son and The Spirit, together, are The Only True God.
