The Bible makes it very clear that every human being has a natural tendency to sin. We all make mistakes and let ourselves be lured away from what we know is right. But, I think it goes even deeper than this.
Our Instincts Are Messed Up
For I know that good itself does not dwell in me, that is, in my sinful nature. For I have the desire to do what is good, but I cannot carry it out. Romans 7:18 NIV
The Apostle Paul says we have a sinful nature. Another word for nature is instinct. This implies that our instinct is corrupt. It is broken.
When we talk about instinct, we usually are thinking about animals. They have certain fixed patterns of behavior that they are born with. These instincts tell them how to act in certain situations. For example, they migrate to a particular place to have their babies. This behavior seems pre-programmed into them. They are born with it.
In the same way, we often say that humans are born with certain instincts for who they are attracted to or how they behave or what gender they identify with. Some assume that if a person is born this way, then it must be okay. It must have been how God intended them to be and therefore cannot be counted against them as sin.
But, unlike the animals, the Bible says our instinct is messed up. Our programming is faulty. We have a sinful instinct. One that has gone wrong. Therefore, we cannot conclude that just because we are born with a propensity to be a certain way that it is okay.
Instinct Is No Excuse for Sin
for all have sinned and fall short of the glory of God Romans 3:23 NIV
To be 100% clear, I’m not picking on any particular group of people. Because, the truth is that we are ALL broken. We all have a sinful nature — a messed up instinct. It is easy to look down our nose at others, but none of us have any right to do this. James 2:10 says, “For the person who keeps all of the laws except one is as guilty as a person who has broken all of God’s laws.” I’m simply pointing out that saying you were born this way is no excuse.
