"Christians certainly know that it is a sin to go around telling lies, but not so many know that it is also a sin to believe lies. Our race fell into sin because they believed a lie (Gen. 3:4-6).
The Roman Christians were told to be on guard against those who with flattering words deceive the naive.
It is a sin to be naive like that (Rom. 16:17-18).
The Colossians were warned against empty deceit (Col. 2:8).
As condemnation, God sent a strong delusion on certain individuals so that they would believe a lie. This was because they refused to love the truth (2 Thess. 2:9-13).
The Galatians were rebuked for believing falsehoods (Gal. 3:1)."
