The words of Isaiah are fulfilled in them, which proclaim: ‘You shall hear by hearing, and not understand; and you shall look with your eyes, and not see; for the heart of these people is hardened, and they can hardly hear with their ears, and they have closed their eyes; lest they see with their eyes, and hear with their ears, and understand with their hearts, and turn back, that I may heal them’ (Matthew 13:14-15; Isaiah 6:9-10). The depravity of many among them is so profound that they deliberately choose to turn a deaf ear to the truth and shut their eyes to the miraculous signs around them, as if afraid that acknowledging them would lead them to turn to God for salvation. Nevertheless, Christ does not reject them; rather, He teaches them about the kingdom of heaven through allegory, allowing them the opportunity to uncover the deeper meanings of the parables if they so desire. Those who genuinely seek to grasp the significance of these teachings will be granted understanding that will grow within them, while those lacking such a desire will remain imperceptive to Christ’s teachings, regardless of their presentation; even the knowledge of God inherent in all people, regardless of their spiritual maturity, will become irrelevant to them and fade away, as if it were taken from them. However, for the Apostles, who left all worldly pursuits to follow Christ and thereby embraced faith in Him with a true yearning to adhere to His teachings, understanding was bestowed upon them. They became capable of perceiving what others could not, for their hearts were open whereas others, lacking faith and desire, hear without hearing and see without understanding. To them, the secrets of the kingdom of heaven were revealed.
