《When You Believe》是1998年梦工厂动画片《埃及王子》的主题曲。创作灵感来自于动画片主角回忆想向上帝祈祷的场景，起初，他们祈祷数夜上帝却未曾应答，最终却坚信，只要相信上帝，奇迹就一定会出现，也就是歌词中的There can be miracles when you believe。
这也是本首歌的主题所在。歌曲的mv在布鲁克林音乐学院拍摄，其中的埃及背景和幕布等灵感皆来自于《埃及王子》，凯利和休斯顿的幕后视频不断穿插在mv当中，整个mv场面庄重不失典雅，最后以炫目的烟火效果和宏大的合声达到高潮。凯利和休斯顿的演唱的独特气质也完美融合，这成为两人难得的合作经典。
When You Believe歌词[中英文版]
Many nights we've prayed 我们祈祷了很多个夜晚;
With no proof anyone could hear 我们祈祷的证据(声音)没有人能听到;
In our hearts a hopeful song 在我们的心中，希望之歌;
We barely understood 我们以前勉强能理解;
Now we are not afraid 现在我们不怕了;
Although we know there's much to fear 虽然我们知道，还有很多可怕的事;
We were moving mountains long 我们一直在移山;
Before we knew we could 早在我们意识到自己有能力之前;
*There can be miracles, when you believe 只要你相信，就会有奇迹;
Though hope is frail, it's hard to kill 希望虽然脆弱，但很难扼杀;
Who knows what miracles you can achieve 谁知道你能创造什么样的奇迹呢;
When you believe, somehow you will 只要你相信，你就能做到;
You will when you believe* 只要你相信，你就能做到;
In this time of fear 在这个充满恐惧的时代;
When prayers so often proves in vain 祈祷往往是徒劳的;
Hope seems like the summer birds 希望好似夏天的候鸟;
Too swiftly flown away 很快就飞走了;
Yet now I'm standing here 但是现在我站在这里;
My heart's so full I can't explain 我的心是那么充实，我都无法解释了;
Seeking faith and speaking words 追寻信仰，并说出;
I never thought I'd say 我从未想过自己会说的话;
Repeat *
They don't always happen when you ask 每当你祈求时，奇迹不总是会发生;
And it's easy to give in to your fear 你很容易向恐惧屈服;
But when you're blinded by your pain 但是，每当你被痛苦蒙住双眼;
Can't see your way safe through the rain 在雨中看不见前方的路是否安全;
Thought of a still resilient voice 想到一个令人振作的声音;
Says love is very near 他说，爱近在咫尺.
