How your conscience and crying child are similar

As the father of two kids, I've experienced a lot of toddler tantrums.

When you hear you child cry the first few times it breaks you up inside.
It becomes soul-destroying when you can't get your precious little bub to stop wailing.

But, as you get older, you begin to become more immune to the crying of your offspring.
You become immune to the immediacy of its noise.

Sure, you still hear the crying, but you get better at either tolerating it or tuning it out alltogether.

In this way, your crying child and your conscience are similar.

You hear both.
Over time, the cutting edge of your conscience, like the early-life crying, can become dulled.
With pre longed exposure, you build up a tolerance to its nudging or can outright ignore it.

I wonder, when it comes to our conscience convicting us of wrongdoing, do we sometime know that if we just endure and rebel long enough, then the voice of our conscience can be drowned out or silenced outright.
