Knowing truth is not the end goal of sanctification – holiness is. "Sanctify them through thy truth, they word is truth." John 17:17 Lack of knowledge is not the problem - lack of wisdom is the problem. Truth revealed by the Holy Spirit of God will cause a person to grow in grace and holiness. Truth in the hands of the devil turns people into arrogant bullies who stay focused on one or a few truths and use them to beat on other people. If the truth turns you into an ogre that hates and destroys other people, you got that truth from the devil, even if it is a truth of God. If God reveals a truth to you it will be manifested by the fruit of the Spirit, which is love, joy, peace, longsuffering, gentleness, ... Beware! The devil can deceive you more easily with truth than he can with lies.
