In high school, I didn’t care about my faith. Did what I wanted. Then, when I was approached with Islamic ideas, they never made sense.
One night, I had the sour realization that I had spoiled and corrupted my heart to the point where right seemed wrong and wrong seemed right. I was sick.
If someone is immersed in a life that is harmful, they shouldn’t expect the advice God gives us to make sense, filtered by a sick heart. Rather, that person should make an effort to purify their life so that the info they’re receiving isn’t being tainted by faulty vision.
It’s of like pouring pure water into a glass filled with dust and dirt - the water is pure and amazing, but the glass will inevitably alter it from pure to undesirable.
May God give us success and guidance.
