音樂劇《天路客》（Pilgrim）改編自名著《天路歷程》，以寓言的方式描繪基督徒一生會經歷的種種考驗。在音樂劇中，屬靈世界裡所有無形的力量都真實地呈現在觀眾眼前。劇中的國王代表上帝，幾乎在整場演出都出現在舞台上。他身穿白衣，積極阻擋敵人的攻擊，溫柔地擁抱那些深感痛苦的人，並勸說其他人行善。儘管國王是個不可或缺的角色，但那些飾演人類的角色卻看不見這位國王，只能看到他做的事所產生的影響。

即使我們看不見上帝這位真正的君王，我們的生活是否反映了祂就在我們的生命裡呢？在需要幫助的時候，先知但以理從一位天上的使者那裡得到了異象（但以理書10章7節），這位使者是來回覆但以理恆切的禱告（12節）。使者解釋說，自己因屬靈的爭戰而耽誤了行程，還好得到天使長的幫助（13節）。使者提醒但以理，儘管他看不見上帝，但處處可以看見上帝看顧與關懷的明證，使者鼓勵他說﹕「大蒙眷愛的人哪，不要懼怕。」（19節）

在《天路客》的結尾，當主角歷經千辛萬苦到達天堂門口的時候，他第一次高興地喊道﹕「我能看見國王了！」讓我們在今日的生活中察覺上帝的作為，直到我們在天上與祂面對面，親眼看見祂。

Pilgrim is a musical based on The Pilgrim’s Progress, an allegory of the life of a believer in Jesus. In the story, all the unseen forces of the spiritual world are made visible to the audience. The character of the King, representing God, is present onstage for almost the entire show. He’s dressed in white and actively blocks attacks from the enemy, tenderly holds those who are in pain, and nudges others to good works. Despite his indispensable role, the main human characters can’t physically see the King, only the effects of what He does.

Do we live as if the true King is active in our lives, even when we can’t physically see Him? In a time of need, the prophet Daniel received a vision from a heavenly messenger (Daniel 10:7) who’d been sent in direct response to his faithful prayers (v. 12). The messenger explained that spiritual warfare had delayed his coming and angelic backup had to be dispatched (v. 13). Daniel was reminded that even though he couldn’t see God, he was surrounded by evidence of His care and attention. “Do not be afraid, you are highly esteemed,” the messenger encouraged him (v. 19). At the end of Pilgrim, when the main character reaches heaven’s door after many tribulations, he joyfully cries out for the first time, “I can see the King!” Until we see Him with our new eyes in heaven, we look for His action in our lives today.
