7 Bible Verses about Those Who Are Liars

But let God be truthful, [even if] everyone [else] is a liar. For it is written [Psa. 51:4], "[God], you should be proven right when you speak, and win [your case] when put on trial."

Even one of their own prophets said, "The people of Crete are always liars, vicious beasts and lazy gluttons."

Now you people have not known Him [i.e., to be your Lord], but I know Him. And if I should say, 'I do not know Him,' I would be a liar like you. But I [do] know Him, and I obey His message.

If a person says, "I love God," yet [in reality] hates his brother, he is a liar. For the person who does not love his brother, whom he has seen, cannot [possibly] love God, whom he has never seen.

Who is the liar? It is the person who denies that Jesus [truly] is the Christ [i.e., God's specially chosen One]. This person is the antichrist [See verse 18]; he is the one who denies [the truth about] the Father and the Son.

The person who says, "I have come to know Him," but does not obey what He commands, is lying [by such a profession], and the truth [about the matter] is not in his heart.

You belong to your father the devil, and you are [always] wanting to do what your father desires. He was a murderer from the [very] beginning [Note: This is probably a reference to Satan's influence on Adam, Eve and Cain in the Garden of Eden] and does not stand for the truth, because there is no truth in him. When he lies, he only speaks what is part of his nature, because he is a liar and the father of [all] liars.
