《感恩的心》的詞曲作者都是關吉伸，由王建龍演唱。以下是歌曲的詞：
我來唱一首歌獻給你
詞中的真心誠意
是我一生愛的感悟
真情實意播著生命旋律
遠遠看著希望我們勇往直前
踏過生命裏每一次感動
你的鼓舞聲影從此伴我一生
最深的感謝心中藏起
讓我們懷著感恩的心上路
再累也是幸福人生裏
歌曲還有英文版，由美國歌手Karen Rodriguez演唱。以下是英文版的部分詞句：
I'm singing a song for you,
With sincerity in my heart,
It's a life lesson I've learned,
And I'll keep it true.
Through hope in the distance,
We'll keep moving forward,
Through every moment of life,
You've given me strength.
Your encouraging words, your presence,
You'll forever be in my heart,
With gratitude I'll keep you.
And I'll take this road with a grateful heart.
