When it comes to expressing one's trust or belief in someone or something, there are various phrases and synonyms that one can use instead of the traditional "hath confidence of." Some of these expressions include "has faith in," "believes in," "puts trust in," "places reliance on," "has reliance on," "has conviction in," "has assurance in," "has a firm belief in," and "has complete trust in." Each of these phrases carries a slightly different nuanced meaning, but all of them convey the same basic idea - a sense of trust, assurance, and reliability. Choosing the right synonym depends on the context, level of informality, and tone of communication that one wants to convey.
