Peter repented of denying Christ and was established as the leader of the apostles.
Judas repented of betraying Christ, hung himself, and went to Hell.
Clearly not all repentance is the kind that leads to salvation. But that raises the difficulty of figuring out whether your repentance is biblical or shallow.
This tract by Jim Elliff is meant to help people answer that question. It is a discussion of repentance, or rather of repenters. On the one side is the repenting repenter, the true Christian, who repents from the heart. On the other side is the unrepenting repenter, the one whose repentance is worthless. If you’re doubting your own salvation, or the salvation of another, this tract will help to make the truth plain.
