Matthew 13:38

“But let your statement be, ‘Yes, yes’ or ‘No, no’; anything beyond these is of the evil one.

but the sons of the kingdom will be cast out into the outer darkness; in that place there will be weeping and gnashing of teeth.”

And He spoke many things to them in parables, saying, “Behold, the sower went out to sow;

And He called them to Himself and began speaking to them in parables, “How can Satan cast out Satan?

And He was teaching them many things in parables, and was saying to them in His teaching,

and said, “You who are full of all deceit and fraud, you son of the devil, you enemy of all righteousness, will you not cease to make crooked the straight ways of the Lord?

The one who does sin is of the devil, because the devil sins from the beginning. The Son of God was manifested for this purpose, to destroy the works of the devil.

By this the children of God and the children of the devil are manifested: everyone who does not do righteousness is not of God, as well as the one who does not love his brother.
