Knowledge means to know Knowledge and ignorance side by side , discernment is required,  ultimately if we want truth God will show us truth .There are ways of becoming truthful and there are ways of becoming duplicitous. Character building along with morality,  ethics and humility open the doors to receive truth and identify it . Unwanted things in the heart means we are not serious about truth, and we can not understand the full path to absolute truth , the unwanted things are like chains that bind us to the world of deceptions.

Srila AC Bhaktivedanta Swami says ..

“Doubt is one of the important functions of intelligence; blind acceptance of something does not give evidence of intelligence. Therefore the word saṁśaya is very important; in order to cultivate intelligence, one should be doubtful in the beginning. But doubting is not very favorable when information is received from the proper source. In Bhagavad-gītā the Lord says that doubting the words of the authority is the cause of destruction.

As described in the Patañjali yoga system, pramāṇa-viparyaya-vikalpa-nidra-smṛtyaḥ. By intelligence only one can understand things as they are. By intelligence only can one understand whether or not he is the body. The study to determine whether one’s identity is spiritual or material begins in doubt. When one is able to analyze his actual position, the false identification with the body is detected. This is viparyāsa. When false identification is detected, then real identification can be understood. Real understanding is described here as niścayaḥ, or proved experimental knowledge. This experimental knowledge can be achieved when one has understood the false knowledge. By experimental or proved knowledge, one can understand that he is not the body but spirit soul.

The Christian bible says to use intelligence, and so does the Srimad Bhagavatam.

Don’t be a blind follower..

Good advice from the Christian bible..

The Bible consistently encourages using your intelligence and reasoning. It values an active mind, urging believers to acquire knowledge, seek understanding, and make intelligent, reasoned choices.Key verses on this topic include:Reasoning and Thinking: “Come now, let us reason together,” says the Lord (Isaiah 1:18).Acquiring Knowledge: “An intelligent heart acquires knowledge, and the ear of the wise seeks knowledge” (Proverbs 18:15).Using Your Mind: “You shall love the Lord your God with all your heart and with all your soul and with all your mind” (Matthew 22:37).Discernment: “Do not be conformed to this world, but be transformed by the renewal of your mind” (Romans 12:2).While the Bible celebrates using your intellect, it also highlights the difference between human intelligence and divine wisdom. It warns against relying solely on human cleverness without moral guidance or humility before God, stating, “The fear of the Lord is the beginning of knowledge” (Proverbs 1:7)…
The Srimad Bhagavatam.
ŚB 2.2.35

bhagavān sarva-bhūteṣu
lakṣitaḥ svātmanā hariḥ
dṛśyair buddhy-ādibhir draṣṭā
lakṣaṇair anumāpakaiḥ

Translation
The Personality of Godhead Lord Śrī Kṛṣṇa is in every living being along with the individual soul. And this fact is perceived and hypothesized in our acts of seeing and taking help from the intelligence.
