some like to imply that the bible lies ..when it says do a certain thing they say .. o
"oh no you don't have to do that ,because their word is greater than God's word and we must follow their opinion not God
we must ignore the word of God ..
but God is not mocked and he will judge according to his own word and not peoples amended opinions
The OP is a little unclear so bear with me. I agree that if a person persists in disobedience that it's unlikely they are truly saved. If there is no evidence of salvation, likely that's because the person is unregenerate. It's like this: If a person says they are saved they are also saying that they "follow Christ." If you live in disobedience then you aren't following Christ. If you don't follow Christ, it's clear that person is not a Christian (a Christ follower).
Our obedience however does not save us. But obedience should naturally follow for someone who is saved. So how should we behave? Which commands to follow? Those questions lead to a legalistic frame-work. That is a dangerous way to approach it. We should live in a way that reflects the mind of Christ.
Philippians 2:
5 Let this mind be in you, which was also in Christ Jesus:
6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
9 Wherefore God also hath highly exalted him, and given him a name which is above every name:
10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;
11 And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
12 Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
13 For it is God which worketh in you both to will and to do of his good pleasure.
