If a person's soul was cursed and they were tortured for the remainder of their lives, would they be condemned to hell or could they be saved?
We must first determine what causes a soul to be cursed. Let's look at the words of the Lord Jesus in Matthew 25:41, "Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels." This describes an event that has not happened yet. It refers to the Lord's judgment of the nations at the end of the Tribulation Period. I encourage you to read Matthew 25:31-46. In this instance, a person's love for the Lord will be determined by how he treats the Lord's people. Those mentioned in verse 41 had treated the Lord's people terribly and had neglected them in their needs. These people were cursed by their own unbelief and actions and sent to a place of "everlasting fire, prepared for the devil and his angels." Notice that this place was not created for people but was created for Satan and his demons. Yet, those who pass from here in unbelief will be sent there for eternity.
I believe it is clear that the only way a person is truly cursed is if he dies in his sins. If a person dies in unbelief, his eventual eternal dwelling place will be Hell, the lake of fire to be 'punished with everlasting destruction from the presence of the Lord.' Any form of abuse, torture, or cruelty upon us has no actual bearing on our salvation. If one is tortured for years by a sadistic person, their salvation is still dependent upon their faith on the Lord Jesus Christ. We read in John 14:6, "Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me." Regardless of how one spends his life, whether it be in the lap of luxury or in a cruel environment, it is faith in the Lord Jesus Christ that will save that person. What is really sad is when someone goes through a life of suffering but refuses to accept Christ as their savior. Besides the sad life on earth, they would also spend an eternity in Hell because of their unbelief.
