To serve GOD is to be a servant of the TRUTH.
To serve the world is to be a servant of Lies.
“Who changed the [TRUTH OF GOD] into a lie, and worshipped and served the creature more than the Creator, who is blessed forever? Amen” (Romans 1:25).
From the beginning of time, there has been the ‘spiritual war’ whether to believe the HOLY ONE OF THE TRUTH (Genesis 2:16–17) or believe the wicked one of the lie (Genesis 3:4), and this war is still raging to this day.
GOD is the FATHER OF TRUTH: “He is the Rock, his work is perfect: for all his ways are judgment: a [GOD OF TRUTH] and without iniquity, just and right is he” (Deuteronomy 22:4).
Devil, aka Satan is the father of lies. Jesus says: “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” (John 8:44).
On the Last Day, the Day of Judgment where every human being ends up FOREVER will be direct result of whether they believed the God of TRUTH or the father of lies.
“For this is good and acceptable in the sight of [GOD OUR SAVIOUR]; who will have all men to be saved, and to come unto the [KNOWLEDGE OF THE TRUTH]” (1 Timothy 2:3-4).
When time ends, for the Children of God: “[TRUTH] shall spring out of the earth; and righteousness shall look down from heaven” (Psalm 85:11).
On the other hand for the children of the devil: “For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, [WHO HOLD THE TRUTH IN UNRIGHTEOUSNESS]” (Romans 1:18).
“And with all deceivableness of unrighteousness in them that perish; [BECAUSE THEY RECEIVED NOT THE LOVE OF THE TRUTH, THAT THEY MIGHT BE SAVED]” (2 Thessalonians 2:10).
“We can do nothing against the truth, but for the truth” (2 Corinthians 13:8). “And ye shall know the truth, and [THE TRUTH SHALL MAKE YOU FREE]” (John 8:32).
“[HE THAT HATH THE SON HATH LIFE]; and he that hath not the Son of God hath not life. [IF THE SON THEREFORE SHALL MAKE YOU FREE, YE SHALL BE FREE INDEED]” (John 8:36).
