What does the Bible say about seeing and hearing the truth?

The ability to see and hear spiritual truth is reserved for believers, as indicated in passages such as 1 Peter 2:7, where it states that Christ is precious to those who believe, but a rock of offense to those who disobey. The natural state of man is a blindness and deafness towards divine truth, which only the Holy Spirit can remedy by granting spiritual sight and understanding. Jesus emphasized this truth, asserting, 'Let him who has ears to hear, let him hear.' This underscores that true comprehension of the gospel involves a work of divine grace within the heart.
