Those who engage in twisting of the gospel, or the inventing of a gospel, or loving a false gospel, are slaves to their notions. They cannot learn the truth while they hold to their own teachings and they cannot escape this hold their own teachings have on them. By their conceit they have fallen into the devil’s trap. He holds them captured. The only escape is to believe in the light of the world, Jesus Christ, and to hold to his teachings. Then the truth will eventually enter their minds and free them from their trap. This must happen in this life, if they are ever to be freed from sin in this life. The next life is too late. Without this escape, they will die in their sins. The same applies to all of us too since we all need the light of the world. We all need his freedom. We all have to escape sin in this life. After this life it is too late because it is not long after death that judgement comes. The way we live now determines what happens then. We need to learn the light and truth now while there is time to stop sinning, otherwise we will die in our sins and face judgement in them.
