Discernment in the Bible refers to the God-given ability to distinguish truth from lies, right from wrong, good from evil, and to know Gods will and direction for our lives. It is the process of making careful distinctions in our thinking about truth, and the ability to decide between truth and error, right and wrong. The word "discern" and its derivatives are translations of the Greek word "anakrino" in the New Testament, which means "to distinguish, to separate out by diligent search, to examine".
Discernment is like the physical senses; to some, it is given in unusual measure as a special grace gift, but some measure of it is essential for us all and must be constantly nourished. The Christian must take care to develop their "sixth sense" of spiritual discernment. Discernment includes the ability to "weigh up" and assess the moral and spiritual status of individuals, groups, and even movements.
According to the New Testament, discernment is not optional for the believer; it is required. Failure to distinguish between truth and error leaves the Christian subject to all manner of false teaching, which leads to an unbiblical mindset and unfruitful and disobedient living. Discernment intersects the Christian life at every point, and Gods Word provides us with the needed discernment about every issue of life.
In summary, discernment in the Bible is the ability to distinguish truth from lies, right from wrong, good from evil, and to know Gods will and direction for our lives. It is the process of making careful distinctions in our thinking about truth, and the ability to decide between truth and error, right and wrong. Discernment is essential for every believer and must be constantly nourished.
