罗马书1:28告诉我们，我们每个人都有一个堕落的头脑。我们用弗洛伊德的防御机制压制，把我们邪恶的思想，感情，冲动压入潜意识的海中。希望这可以帮助我们活出讨神喜悦的生命。但是，这些想法，感受，和冲动仍驱动和控制我们。他们在我们不知不觉中冒出来，这就是为什么我们充满嫉妒，凶杀，争竞，欺骗和恶意。我们是讒毀的，背後說人的，怨恨神的，傲慢无礼，傲慢自负的（罗马1：29-30）。

被压抑的感情，冲动迸发出来，压倒我们努力保持的“圣洁”。我们知道上帝的正义法令，那些做这样事情的人面对死亡刑法（罗马1:32），但我们无法帮助自己避免这刑法。

弗洛伊德的心理结构模型有三部分：ID，本我，和超我。 ID工作在性和死亡驱动的潜意识中; 本我努力在满足社会可接受的方式下满足ID需求; 超我是负责确保道德标准得到遵守。 ID是核心，而我们都因为罪拥有败坏的ID。我们唯一的希望就是接受耶稣为我们的救主，使他的生命能活在我们里面来代替我们ID的功能。

Romans 1:28 tells us that everyone of us has a depraved mind. We use repression, Freud’s Defense Mechanisms, to put our evil thoughts, feelings, urges in the unconscious sea and hoping this can help us to live a life to please God. But those thoughts, feelings and urges are still driving and controlling us. They come out of us unconsciously and that is why we are full of envy, murder, strife, deceit and malice. We are gossips, slanderers, God-haters, insolent, arrogant and boastful according to Roman 1:29-30.

The repressed feelings, urges burst out and suppress the “holiness” we strive to maintain. We know God’s righteous decree that those who do such things deserve death, Roman 1:32, but we cannot help us to avoid God’s death penalty.

Freud’s mental structural model consists of the three parts: ID, EGO and SUPER-EGO. ID operates at the unconscious level with Sex and Death drives; the ego will try to satisfy the ID in a socially acceptable way; the super-ego is responsible for ensuring moral standards are followed. ID is the driving core and we all have a corrupted ID because of the sin. Our only hope is to accept Jesus as our savior so that his life can live inside of us to replace the function of our instincts, ID.
