Christians who speak not the truth hateth his brother
Galatians 4:16 "Am I therefore become your enemy, because I tell you the truth?"
Apostle Paul tells us in this verse that as born again believers, we are expected to stir up enmity from those around us because we speak the truth from every word of God in the 66 books of the Holy Bible.
1 Timothy 3:15 “But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.”
As the living body of Christ, born again believers are the pillar and the ground of "the truth". That means that the church of the living God will always stand on every word of God (the truth), and that without exception.
Proverbs 8:13 “The fear of the LORD is to hate evil: pride, and arrogancy, and the evil way, and the froward mouth, do I hate.”
The love of the truth is to fear the LORD, and the fear of the LORD is to hate evil. Therefore, if a thing is not true, it is the duty of the church of the living God to reject it as false without compromise, because it is in the nature of every born again believer to love the truth and hate evil.
Psalms 119:104 “Through thy precepts I get understanding: therefore I hate every false way.”
The love of the truth is to hate every evil way, and every false way. There is only one way to God and that is through faith in every word of God in the 66 books of the Holy Bible.
John 14:6 "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me."
The opposite of “every false way” is Jesus Christ (“the truth”), Jesus being the Word of God (John 1:1; 1 John 5:7).
Proverbs 8:36 “But he that sinneth against me wrongeth his own soul: all they that hate me love death.”
The love of "the truth" (Jesus Christ) is to love life. To hate "the truth" (every word of God) is to love death.
James 2:8 If ye fulfil the royal law according to the scripture, Thou shalt love thy neighbour as thyself, ye do well:
The love of “the truth” (Jesus Christ) is a sure mark of a born again believer. To love death is to hate Jesus Christ who came to give himself for the world. Therefore, it is in the nature of every born again believer who love the truth to love his neighbour as himself. He does not want his neighbour to get in harms way.
2 Thessalonians 2:10 “And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.”
This verse tells us that those who have not the love of the truth are not born again believers. John further elaborates:
1 John 3:14-15 “We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. 15 Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.”
One of the surest marks of a truly born again believer is that he loves his brother, and because he loves his brother, he will speak the truth, as in:
Proverbs 27:5-6 "Open rebuke is better than secret love. 6 Faithful are the wounds of a friend; but the kisses of an enemy are deceitful."
He will rebuke his friend in love with the truth, because he loves him, and his love is genuine love. That would be Apostle Paul in Galatians 4:16 who became an enemy of those who hate the truth for the word's sake.
Ephesians 4:15 "But speaking the truth in love, may grow up into him in all things, which is the head, even Christ:"
To love someone is to tell him the truth (hoping that someday he will repent), even if it will make that person your enemy.
Ecclesiastes 12:13 "¶ Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man."
The whole duty of a born again believer is to fear God and keep his commandments, and to fear God is to speak the truth in love without the fear of men.
1 John 3:14-15 “We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death. 15 Whosoever hateth his brother is a murderer: and ye know that no murderer hath eternal life abiding in him.”
John 8:44 “Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.”
Christians who speak not the truth hateth his brother, and whosoever hateth his brother, are not born again believers, but children of the Devil. Likewise, churches that failed to stand as pillars and grounds of "the truth" (every word of God) are not real churches, but synagogues of Satan, because no murderer hath eternal life abiding in him.
