美元上都写着 In God We Trust （= We Trust in God）。以前开店的人经常会遇到顾客要求赊账的。为了让顾客“免开尊口”、杜绝赊账，店家就在店里挂个这样的大牌子：
"我相信你说的话"，我会说 I trust you。 但是 to trust in somebody，那就是可以以命相托的了。基督徒说“信主、把自己托付给主”，就是这个意思。
believe somebody 与 believe in somebody 的区别，也与上述这两者差不多。只是 trust 比 believe 更加高一级而已。
以前有一首老歌，是情歌， I Believe In You 相当好听，不妨找来听听，看着下面的歌词听完，你这辈子都不会搞混 believe 与 believe in 的区别了： “有些东西，我是爱信不信、无所谓 --- 那都是 'believe'；但是对你, I believe IN you".
I Believe In You
I don't believe in superstarsOrganic food and foreign carsI don't believe the price of goldThe certainty of growing oldThat right is right and left is wrongThat north and south can't get alongThat east is east and west is westAnd being first is always best
But I believe in love, I believe in babiesI believe in mom and dad, and I believe in you
Well I don't believe that heaven waitsFor only those who congregateI like to think of God as loveHe's down below, He's up aboveHe's watching people everywhereHe knows who does and doesn't careAnd I'm an ordinary manSometimes I wonder who I am
But I believe in love, I believe in musicI believe in magic, and I believe in you
I know with all my certainty what's goin'With you and me is a good thingIt's true, I believe in you
I don't believe virginity Is as common as it used to beIn working days and sleeping nightsThat black is black and white is whiteThat Superman and Robin HoodAre still alive in HollywoodThat gasoline's in short supplyThe rising cost of getting by
But I believe in love, I believe in old folksI believe in children, I believe in you
I believe in love, I believe in babiesI believe in mom and dadAnd I believe in you
