The human mind-since the beginning- is defective and limited. The mind was better in the beginning when God created it, for God saw everything that He had made, and indeed it was very good. The human mind-after its creation- was subject to sin and to the world with its ideas, researches, experiences, customs, traditions, systems and formalities which had an impression on the mind . This made the mind liable to issue wrong judgements and made it unable to comprehend or approach God on its own. Those who think themselves wise and intelligent and trust in their own wisdom and intellect are the farthest from spiritual and theological matters. Therefore St. Paul the Apostle said,: "And my speech and my preaching were not with persuasive words of human wisdom but in demonstration of the Spirit and of power...", "... we also speak, not in words which man's wisdom teaches but which the Holy Spirit teaches, comparing spiritual things with spiritual". (1 Cor. 2:4,13)
