He became such by open rebellion against the truth, a rebellion in the face of light and knowledge. Although he knew God and had been taught the provisions of the plan of salvation, he defied the Lord and sought to enthrone himself with the Lord's power. He thus committed the unpardonable sin. In rebellion with him were one-third of the spirit hosts of heaven. Those in this life who gain a perfect knowledge of the divinity of the gospel cause, a knowledge that comes only by revelation from the Holy Ghost, and who then link themselves with Lucifer and come out in open rebellion, also become sons of perdition.
Perdition is both a place and a spiritual condition.
This future kingdom of the devil will be devoid of any of the Spirit and glory of God. Fire and brimstone characterize the person, not the place. In sinning against the revelations of the Holy Ghost, they have sinned against the greater light and knowledge of God. They willfully and utterly pervert principles of righteousness and truth with which they were once endowed, and transform them into principles of evil and deception. Few individuals have been identified as sons of perdition.
