The Children of GOD are the Children of Obedience.
“Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world” (1 John 4:4). “For ye are all the children of God by [FAITH IN CHRIST JESUS]” (Galatians 3:26).
The children of the devil are children of disobedience.
“They are of the world: therefore speak they of the world, and the world heareth them” (1 John 4:5).
“In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother. For this is the message that ye heard from the beginning, that we should love one another. Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother’s righteous” (1 John 3:10-12).
“Marvel not, my brethren, if the world hate you” (1 John 3:13).
“We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error. Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.
He that loveth not knoweth not God; for God is love. In this was manifested the love of God toward us, because that God sent his only begotten Son into the world, that we might live through him” (1 John 4:6-9).
On the Last Day, the Day of Judgment only the Children of God: the Children of Obedience: the Children of the Kingdom: THE RIGHTEOUS will be SAVED!
“Jesus Christ the same yesterday, and today, and forever” (Hebrews 13:8) explains, saying: “He that soweth the good seed is the Son of man; the field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one; the enemy that sowed them is the Devil; the harvest is the end of the world; and the reapers are the angels. As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; and shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. Then shall the righteous shine forth as the sun in the kingdom of their Father” (Matthew 13:37–43).
