As you damage Isaac, he goes from being curled up on the floor, to ascending into the light above. I believe this signifies two things. Firstly it signifies Believing himself to be incorrupt of sin and that he will ascend to heaven when he dies. but I also think it is a metaphor for Isaac Isaac ascending from the box to the outside world. When you beat Isaac he is leaving box, and going back up to the light of the world above. We are given a cutscene of Isaac studying the bible after leaving the box.
在你伤害以撒的过程中，他从蜷缩在地板上，变成飞到上方照下的圣光的形态。我认为这表现了两点。首先以撒认为他是纯洁无罪的，他死后会升入天堂。我同时觉得这是一个隐喻，喻示以撒爬出箱子，回到现实。当你打败以撒，他的确离开了箱子，回到光明中。我们接着看到以撒离开箱子后研读圣经。
After reading through the Bible. Isaac comes to the realization that he he is indeed "corrupted with sin". The real world has hurt him deeply once again. He turns to the box once more to go back to escape reality and his own self whome he hates.
读完圣经，以撒意识到，他的的确确是“恶贯满盈”。真相再次深深地伤害了他。他又一次回到了逃避现实和他所厌恶的自己的状态里。

When you beat the cathedral 6 times you unlock the polaroid. A picture of a happy moment with Isaac, his mom and... Dad?
当你打通天堂6次，你会解锁全家福。一张记录幸福的照片，上面有以撒，他的妈妈和……爸爸?
The polaroid depicts one moment in Isaac's life where he was not unahppy, where the outside world was not a horrible place for him. The polaroid shows the turning point in isaac's life and how his life took a turn for the worst. His dad abandoned Isaac and his mother in some way, leaving both of them strucken with grief. Isaac's mother became bitter and her entire life now revolves around religion. Isaac was then ignored and neglected and retreated to his world of games and toys. His depression caused him to become the victim of the bullying of the other kids. Which leads us back to the chest.
全家福描绘了以撒生活中他开心的日子，那时候外面的世界还不是那么糟糕。这张全家福展示了以撒人生中的转折点，以及他的生活如何转眼沉入地狱。他的爸爸以某种方式抛弃了以撒和他的妈妈，留下痛苦不堪的两人。以撒的妈妈变得乖戾，她的全部生活都绕着宗教转。以撒被忽视，并退缩到他游戏和玩具的世界里。他的压抑情绪导致他被其他的孩子欺负。这样就又回到了箱子的话题上。
