DISCERNMENT AND RELATIONSHIP
“But he who is spiritual discerns all things,
and he himself is judged by no one.”
1 Corinthians 2:15
Discernment has nothing to do with intellectual prowess. True discernment is the aggregate result of an individual’s walk and life in Christ. Many today have confidence in their spiritual condition due to the overflow of teachings readily available to all. Any teaching that does not bring a corresponding measure of the “fear of the Lord” is bereft of truth. The foundation of a discerning life is built upon the fear of the Lord. (Proverbs 2:3-13)
Discernment requires a walk and an abiding in Him; the things of God will always culminate in the character of Christ. The very essence of truth is Christ who is the Truth. Whenever an expression is in conflict with His nature or character, it will be exposed.
Discernment is a consequence
of our abiding in Him.
Discernment is a faculty developed over time (see note below). It is the natural function of a life which has grown in its relationship with Christ Himself. This sounds trite, but it is a knowing which is the fruit of relationship; not an accumulation of knowledge about Him on an intellectual level. A carnal familiarity with God produces pride, self-assurance and an inflated view of self, whereas a true knowledge of God fills the heart with the wonder of Christ Himself. It is from this place of vital, intimate relationship that all things are compared with Him who is true.
“Which things we also speak,
not in words taught in human wisdom,
but in Words taught of the Holy Spirit,
comparing spiritual things with spiritual things”
1 Corinthians 2:14
Words, apart from the power and unction of the Holy Spirit, will leave people incapable of true discernment. Knowledge is a deceptive thing because it gives the perception that having a familiarity with the things of God alone is a safeguard. Words taught by the Holy Spirit produce a life of obedience which alone brings us into relationship with the living Christ. Obedience is the way into a life of friendship and relationship with God.
“You are my friends,
if you do whatsoever I command you”
John 15:14
A disobedient life will never have the true faculty of discernment because it is does not have an experiential identification with Christ. Friendship with God is revealed in an obedient life. Obedience is the fruit of a life that loves God more than itself. True discernment cannot be disassociated from obedience and the fear of the Lord.
Note: Discernment of a diligent believer is developed over time by its constant use from which a growing sensitivity to Him and His ways is fostered:
“But strong meat belongeth to them that are of full age,
even those who by reason of use
have their senses exercised to discern
both good and evil”
Hebrews 5:14
