leap of faith 一百八十度轉變；改弦更張；信仰的飛躍；儘管沒有理由，但還是堅信

解釋：
Leap of faith - Wikipedia, the free encyclopedia: "A leap of faith, in its most commonly used meaning, is the act of believing in something without, or in spite of, available empirical evidence. It is an act commonly associated with religious belief as many religions consider faith to be an essential element of piety."

例句：

Take a leap of faith and trust them. 來個一百八十度的轉彎，採取信任他們的態度。
