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.

Therefore I will always remind you about these things, even though you know them and are established in the truth you have.

a wise man will listen and increase his learning,
and a discerning man will obtain guidance—

Don’t rebuke a mocker, or he will hate you;
rebuke a wise man, and he will love you.

My brothers, I myself am convinced about you that you also are full of goodness, filled with all knowledge, and able to instruct one another.

Now I want to remind you, though you know all these things: The Lord first saved a people out of Egypt and later destroyed those who did not believe;

I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.

a wise man will listen and increase his learning,
and a discerning man will obtain guidance—

Don’t rebuke a mocker, or he will hate you;
rebuke a wise man, and he will love you.

My brothers, I myself am convinced about you that you also are full of goodness, filled with all knowledge, and able to instruct one another.

Therefore I will always remind you about these things, even though you know them and are established in the truth you have.

Instruct a wise man, and he will be wiser still;
teach a righteous man, and he will learn more.

Then the eyes of those who see will not be closed,
and the ears of those who hear will listen.

They will never follow a stranger; instead they will run away from him, because they don’t recognize the voice of strangers.”
