And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
1 Kings 22:7
But Jehoshaphat asked, "Isn't there a prophet of Yahweh here any more? Let's ask him."
If you stop listening to instruction, my son, you will stray from the words of knowledge.
Then He said to them, "Pay attention to what you hear. By the measure you use, it will be measured and added to you.
Therefore, take care how you listen. For whoever has, more will be given to him; and whoever does not have, even what he thinks he has will be taken away from him."
And He personally gave some to be apostles, some prophets, some evangelists, some pastors and teachers,
for the training of the saints in the work of ministry, to build up the body of Christ,
until we all reach unity in the faith and in the knowledge of God's Son, [growing] into a mature man with a stature measured by Christ's fullness.
Then we will no longer be little children, tossed by the waves and blown around by every wind of teaching, by human cunning with cleverness in the techniques of deceit.
But speaking the truth in love, let us grow in every way into Him who is the head-- Christ.
Therefore as you have received Christ Jesus the Lord, walk in Him,
rooted and built up in Him and established in the faith, just as you were taught, and overflowing with thankfulness.
Be careful that no one takes you captive through philosophy and empty deceit based on human tradition, based on the elemental forces of the world, and not based on Christ.
For in Him the entire fullness of God's nature dwells bodily,
and you have been filled by Him, who is the head over every ruler and authority.
2 Timothy 3:5-7
holding to the form of religion but denying its power. Avoid these people!
For among them are those who worm their way into households and capture idle women burdened down with sins, led along by a variety of passions,
always learning and never able to come to a knowledge of the truth.
2 Timothy 4:3
For the time will come when they will not tolerate sound doctrine, but according to their own desires, will accumulate teachers for themselves because they have an itch to hear something new.
1 Peter 2:1-3
So rid yourselves of all wickedness, all deceit, hypocrisy, envy, and all slander.
Like newborn infants, desire the unadulterated spiritual milk, so that you may grow by it in [your] salvation,
since you have tasted that the Lord is good.
1 John 2:19
They went out from us, but they did not belong to us; for if they had belonged to us, they would have remained with us. However, they went out so that it might be made clear that none of them belongs to us.
1 John 2:21
I have not written to you because you don't know the truth, but because you do know it, and because no lie comes from the truth.
1 John 4:5
They are from the world. Therefore what they say is from the world, and the world listens to them.
1 John 4:6
We are from God. Anyone who knows God listens to us; anyone who is not from God does not listen to us. From this we know the Spirit of truth and the spirit of deception.
I know your works, your labor, and your endurance, and that you cannot tolerate evil. You have tested those who call themselves apostles and are not, and you have found them to be liars.
