God is truth. He abhors lying. The devil is the father of lies.

The truthful lip shall be established forever, but a lying tongue is but for a moment. (Proverbs 12:19)

Blessed are you when they revile and persecute you, and say all kinds of evil against you falsely for My sake. (Matthew 5:11)

Therefore, putting away lying, "Let each one of you speak truth with his neighbor." for we are members of one another. (Ephesians 4:25)

But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death. (Revelation 21:8)
