”When I first thinking about writing a theme song for the upcoming evangelization concert, I asked myself, "How can I be a witnesses of God?" The first thing that came to my mind is the new commandment. In the bible, Jesus says, "I give you a new commandment: love one another. As I have loved you, so you also should love one another." (John 13:34) I believe that basically summarize our Catholic faith. With the help of Holy Spirit, I wrote the song immediately. "We are the Witnesses" is a song that represents what I truly believe in. As we love one another, forgive our enemies, praise the Lord, we basically is the witnesses of God. Moreover, this is a very joyful song, I hope everyone can feel that it is very happy to become God's witnesses.

當我正在創作是次音樂會的主題曲時，我問自己：「我如何能夠成為天主的見證呢？」 第一個意念走進我腦袋的是「新誡命」。 在聖經中，耶穌說：「我給你們一條新誡命：你們該彼此相愛如同我愛了你們，你們也該照樣彼此相愛。」﹝若13：34﹞ 我相信愛是我們天主教誡命的總結。當我想到這裏的時侯，在聖神的引領之下，我很快便完成創作這首歌。「我們就是見證」是一首寫出我自己信念的歌。「我們愛人如己 ，我們寬恕仇敵，我們讚美天主﹍」基本上，這就是成為見證者的元素。 加上這首歌的感覺是很輕快的，我希望大家能夠感受到為作主作見證是多麽快樂的。”
