Spiritual blindness vs. spiritual insight

وَمَا يَسْتَوِى ٱلْأَعْمَىٰ وَٱلْبَصِيرُ وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ وَلَا ٱلْمُسِىٓءُ ۚ قَلِيلًا مَّا تَتَذَكَّرُونَ

And not equal are the blind and the seeing, nor are those who believe and do righteous deeds and the evildoer. Little do you remember.
