I have not written to you because you don't know the truth, but because you know it, and because no lie is of the truth.
Therefore I will not be negligent to remind you of these things, though you know them, and are established in the present truth.
that the wise man may hear, and increase in learning; that the man of understanding may attain to sound counsel:
Don't reprove a scoffer, lest he hate you. Reprove a wise man, and he will love you.
I myself am also persuaded about you, my brothers, that you yourselves are full of goodness, filled with all knowledge, able also to admonish others.
Now I desire to remind you, though you already know this, that the Lord, having saved a people out of the land of Egypt, afterward destroyed those who didn't believe.
