there is in essence 3 different gospels being taught.
1. Licentiousness - also called easy believism or cheap grace says you can basically say a sinners prayer and live however you want. Your saved. Jude condemned this gospel in his book. and James called everyone to test their faith in his book to make sure we do not have this type of "dead" faith,
2. Legalism - This gospel says we are saved by grace plus works. It states that faith is required. but that is not all. We also have to produce works. The amount of works varies from denomination to denomination. I have seen a vast list of things we must do from the jews to the catholics, to as little as we just need to be baptized in water. the amount of works does not matter, the fact they are saying we begin in the spirit (grace through faith) but must perfect in the flesh (our own works) makes it a legalistic gospel. and paul calls them fools.
3. Grace - This gospel say no one is worthy, nor will they ever be worthy, that we all have sinned and fall short of the glory of God, That because of this, we are all dead in tresspasses and sins and have no hope. we are poor in spirit (bancrupt) and have nothing to offer God. But God in his riches of grace and mercy and love sent his son to die in our place. that whoever believes in him with true saving faith. will never suffer the punishment we all deserve (eternal death) but are risen to new life, saved and given eternal life. not based on what we do, on how good we are. or what we do not do. but based on his mercy and grace, for it is by grace we have been saved, through faith. There are a few denominations that teach this gospel. other they may differ on other doctrines, they have this gospel. so are united in this
only one of the above saves. As paul said, if anyone teaches a different gospel. may they be damned..Each one of us will be held accountable for which Gospel we placed our faith in.
