There is a vast number of “Discernment” ministries out there and this is wonderful, but we must guard not to fall into a trap of un Biblical discernment. I was there once myself and have fallen hard believe me. Be discerning when you visit a “Discernment” blog/website. There are few Biblical ones out there. To speak the truth in love should be foremost the  most outstanding character when warning others of false teachings.

Eph 4:15 Rather, speaking the truth in love, we are to grow up in every way into him who is the head, into Christ, – Gills Commentary  explains it so clearly. ~ 

Ephesians 4:15
But speaking the truth in love,…. Either Christ himself, who is the truth, and is to be preached, and always spoken of with strong affection and love; or the Gospel, the word of truth, so called in opposition to that which is false and fictitious; and also to the law, which is shadowish; and on account of its author, the God of truth, and its subject matter, Christ, and the several doctrines of grace; and because the spirit of truth has dictated it, and does direct to it, and owns and blesses it: this, with respect to the ministers of the Gospel, should be spoken openly, honestly, and sincerely, and in love to the souls of men, and in a way consistent with love, in opposition to the secret, ensnaring, and pernicious ways of false teachers; and with respect to private Christians, as they are to receive it in love, so to speak of it to one another from a principle of love, and an affectionate concern for each other’s welfare, to the end that they

may grow up into him in all things which is the head, even “Christ”: the work of grace upon the soul is a gradual work, and an increase of this in the exercise of faith, hope, love, and spiritual knowledge, is a growth; and this is a growth in all things, in all grace, as in those mentioned, so in others, as humility, patience, self-denial, resignation of the will to the will of God, and especially the knowledge of Christ; for it is a growing into him, from whom souls receive all their grace and increase of it; for he is the head of influence to supply them, as well as the head of eminence to protect them; see Eph_1:22 and now the preaching of the Gospel, or the sincere speaking of the truth, is the instrumental means of such growth.

We also read :

2Timothy 2:22-26 So flee youthful passions and pursue righteousness, faith, love, and peace, along with those who call on the Lord from a pure heart. (23) Have nothing to do with foolish, ignorant controversies; you know that they breed quarrels. (24) And the Lord’s servant must not be quarrelsome but kind to everyone, able to teach, patiently enduring evil, (25) correcting his opponents with gentleness. God may perhaps grant them repentance leading to a knowledge of the truth, (26) and they may come to their senses and escape from the snare of the devil, after being captured by him to do his will.

It is also a sin to be undiscerning we must test everything to see it is from God, be like the Berean’s . Acts 17:11  Now these Jews were more noble than those in Thessalonica; they received the word with all eagerness, examining the Scriptures daily to see if these things were so. 

Romans 1:26-32

²⁶ For this reason God gave them up to vile passions. For even their women exchanged the natural use for what is against nature. ²⁷ Likewise also the men, leaving the natural use of the woman, burned in their lust for one another, men with men committing what is shameful, and receiving in themselves the penalty of their error which was due.

1John 4:1 Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.

Jude 1:1-25  Jude, the servant of Jesus Christ, and brother of James, to them that are sanctified by God the Father, and preserved in Jesus Christ, and called:  (2)  Mercy unto you, and peace, and love, be multiplied.  (3)  Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints.  (4)  For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ.

Right now, truth is under attack, and it’s going on within the boundaries of evangelicalism. There’s a lot at stake and there’s no middle ground—no safe zone for the uncommitted in this war.

John MacArthur has written this book to unveil the enemy’s tactics and equip you to fight. Here’s what you’ll learn:

– The pitfalls of postmodern thinking.
– The inherent flaws of the Emerging Church Movement.
– The historic skirmishes in the truth war and their effect on the contemporary church.
– The vital importance of truth and certainty in a postmodern age.

My fave quote from the book :

(Quote) Still, overzealousness is clearly a danger we need to guard against carefully. There are indeed some full-time critics operating today, always looking for a fight, taking fleshly delight in controversy merely for controversy’s sake, and making judgements that may be too harsh. Don’t fall into the trap of assuming that most censorious and nit-picking opinions are automatically the most “discerning” ones. Watch out for the person who shows no caution or restraint about making severe judgements and yet claims to be a “discernment” expert. True discernment is gained by applying our hearts and minds to biblical wisdom, not fostering a critical spirit.

As a matter of fact, Scripture says that those who are merely pugnacious or quarrelsome are unfit for spiritual leadership (1 Timothy 3:3). When Paul laid out the qualifications for church leaders, he was emphatic about this. “ A servant of the Lord must not quarrel but be gentle to all, able to teach, patient, in humility correcting those who are in opposition, if God perhaps will grant them repentance, so that they may know the truth”. (2 Timothy 2:24-25). That is the spirit we must cultivate. Contending earnestly for the faith does not require us to become brawlers. Let’s acknowledge that as plain and possible never lose sight of it. (End Quote)(Page 135, The Truth War by John MacArthur)
