all who are saved do obey him
they are not saved because they obey him (except for obedience to the gospel, which is believe on the name of Jesus and you will be saved)
As Paul said to the Corinthian church, when he spoke of sins, and who people were and that hey would not enter,
he he told them, and such were som of you, but you were washed, but you were sanctified, but you were justified,
he never said they stiped thise sins, some still struggle with those sins, he said those sins were not who they were anymore, the were new creatures
