当你 take a leap of faith, 这就意味着你对一件事情有信心，准备搏一搏，虽然这是属于比较冒险的行为。

例句

I took a leap of faith by buying shares in my friend's new company.

I've been offered a new job but I really don't know what it will be like. It's a real leap of faith.

I think I'll have perm. It's a leap of faith but I hope it looks OK.

请注意

如果一件事情是 done in good faith，这就是说人们相信做完了这件事将会有好的结果。

I came in good faith and offered to help but they were very rude to me.
