We do all sin--we have all done gross sins in our past hopefully, and not in the present
1John 3--is a mirror for all to peer into--it teaches who are the children of God and who are the children of the devil---it teaches--- its impossible for a child of God to practice even 1 sin.( I believe this is speaking about the gross sins that Gods word teaches--will not enter his kingdom
The key to 1 Jn 3:9-10; is the word "practice". (NASB)
1 Jn 3:9; No one who is born of God
practices sin, because His seed abides in him; and he cannot sin, because he is born of God.
1 Jn 3:10; By this the children of God and the children of the devil are obvious: anyone who does not
practice righteousness is not of God, nor the one who does not love his brother.
Making a mistake every once in a while is quite different from willfully "practicing" sin.
-I am 100% confident the brothers in Christ would never do that, and Jesus would not condone that in front of the eyes of all creation for an iota of a second. the spirit of the antichrist is what causes fear, hate, calamity,division. The spirit of Jesus is love,unity, and peace at all times.
Yet Jesus drove the money lenders from the temple with a scourge (whip) and turned over their tables and called them thieves.
He called the Pharisees a brood of vipers and sons of hell.
Rev 19:11; And I saw heaven opened, and behold, a white horse, and He who sat on it is called Faithful and True, and in righteousness
He judges and wages war.
Rev 19:12; His eyes are a flame of fire, and on His head are many diadems; and He has a name written on Him which no one knows except Himself.
Rev 19:13; He is clothed with a robe dipped in blood, and His name is called The Word of God.
Rev 19:14; And the armies which are in heaven, clothed in fine linen, white and clean, were following Him on white horses.
Rev 19:15; From His mouth comes a sharp sword, so that with it
He may strike down the nations, and He will rule them with a rod of iron; and He
treads the wine press of the fierce wrath of God, the Almighty.
Rev 19:16; And on His robe and on His thigh He has a name written, "KING OF KINGS, AND LORD OF LORDS."
Even the prince of peace bears a sword and strikes down the nations and wages war. Even Jesus "treads the wine press of the fierce wrath of God".
Also keep in mind God commanded the Israelite's to go to war over 16 times in the Old Testament.
Jesus is not peace at any cost. Jesus is righteous and Holy at any cost. (even His own life).
