“The Four Perversions of Grace” linked below. It summarizes the following errors and how they interrelate:

1. Basic salvation by works (common forms include water baptism or public confession of Christ as prerequisites for salvation)
2. Arminianism – denial of eternal security (common forms include serious sin or apostasy result in loss of salvation)
3. Bi-lateral contract salvation (common forms include repenting of sins or committing ones life to Christ in order to be saved)
4. The Perseverance of the Saints (the belief that genuine saving faith will always produce visible and lasting results in a person’s life. Therefore, serious or habitual sin would prove that true conversion never happened – that the person was never saved)
