Regarding "reprobate" doctrine of Steven Anderson. Specifically Romans 1.
Ever notice that the context of Romans 1 is not unsaved people, but saved people?
How? It says they that know God are the ones that are reprobated.
21 Because that, when THEY KNEW GOD, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened.
And this is life eternal, that THEY MIGHT KNOW thee the only true GOD, and Jesus Christ, whom thou hast sent.
It says here they are covenantbreakers:
Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
16 To deliver thee from the strange woman, even from the stranger which flattereth with her words;
17 Which forsaketh the guide of her youth, and forgetteth the COVENANT OF HER GOD.
But the clincher here is in the next chapter:
1Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things.
Paul literally says you, whoever was reading, as a saved person, are guilty of the same things.
Reprobation has more to do with the saved rejecting God, than the unsaved rejecting God.
1 Corinthians 5:5
5 To deliver such an one unto Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.
