ANSWER: Some fail to see because they do not study the scriptures as commanded (Acts 17:11; II Timothy 2:15). These and others are often led into error by false teachers (II Peter 2:1; I John 4:1). These teachers, through the god of this world, hide the truth of the gospel from those who are lost, so that “the light of the glorious gospel of Christ, who is the image of God, should not shine unto them (II Corinthians 4:4). This is the reason why we always need to be careful not to “believe every spirit, but try the spirits whether they are of God: because many false prophets are gone out into the world” (I John 4:1).
