what does this song mean?

全曲有點長，只能簡約把每段的大意表示

Many nights we've prayed
With no proof any one could hear
In our hearts a hopeful song we barely understood
Now we are not afraid
Although we know there's much to fear
We were moving mountains long
Before we, we knew we could, oh
我們雖然不斷祈禱未知有否被聽見在心裏抱著我們不明白的希望之歌雖然面對很多恐懼，但我們當下不害怕在我們面前的大山(難關)是可以移去(除去), 我們能夠做到的啊
There can be miracles
When you believe
Though hope is frail
It's hard to kill
Who knows what miracles
You can achieve
When you believe
Some how you will
You will when you believe, ooh
當你相信的話，奇蹟是會發生的雖然希望渺茫 卻不會被消滅你可知當你相信的話你可以造出甚麼奇蹟當你相信的話，必定可以啊
In this time of fear
When prayer so often proves in vain
Hope seems like a summer bird
Just swiftly flown
And now I'm standing here
My heart's so full, I can't explain
Seeking faith and speaking words
I never thought I'd say
在這恐懼的時刻連祈禱都似乎無用希望只像小鳥閃飛而過現在我不能解釋為何能全心追求信心並講出不可思議的話
There can be miracles
When you believe
Though hope is frail
It's hard to kill
Who knows what miracles
You can achieve
When you believe
Some how you will
You will when you believe
當你相信的話，奇蹟是會發生的雖然希望渺茫 卻不會被消滅你可知當你相信的話你可以造出甚麼奇蹟當你相信的話，必定可以啊

Oh, oh

They don't always happen when you ask, ooh
And it's easy to give in to your fears
But when you're blinded by your pain
Can't see your way to get through the rain
A small, but still, resilient voice
Says love is very near, oh
奇蹟不常在我們要求時出現啊因此你便容易被害怕勝過不過當你痛苦沉鬱在風雨中方向迷失仍有一把微小肯定的聲音告訴你有愛在身邊啊
(There can be miracles, when you believe)
Oh, when you believe, oh
(Though hope is) frail
It's hard, (to kill) to kill, oh
Who knows what miracles
You can achieve
When you believe
(Some how you will)
Some how, some how, some how
You know, you know
You will when you believe
[最後副歌大意相同]當你相信的話，奇蹟是會發生的雖然希望渺茫 卻不會被消滅你可知當你相信的話你可以造出甚麼奇蹟當你相信的話，必定可以啊

You will when you, believe
Ooh, you just believe
You will when you, believe只要相信啊

歌曲來自《埃及王子》電影主題曲

此曲原曲為 mariah carey 及已故 whitney houston 為1998年動畫電影 "埃及王子" 合唱的插曲之一. 由於是聖經故事, 所以歌詞內容完全是圍繞信心及信仰, 詳見附上連結~
