No, we know the passage says that ... "he that hath suffered in the flesh hath ceased from sin;"
You are just not believing what the Word of God says here.
In fact, we know that "ceasing from sin" is true because this truth is also confirmed for us in Galtians 5:24, too. For it says they that are Christ's have crucfied the affections and lusts.
You either misunderstood me or you intentionally are trying to twist my words to your advantage. That is not what I said. I said Christ suffered in doing good. That does NOT mean Christ suffered SO AS to do good. Christ suffered WHILE doing good because doing good is a part of Christ natural being. Christ cannot sin because He is the eternal uncreated Son of God (Who is the Second person of the Godhead) who came down into the flesh by way of a virgin named Mary.
I can say the same for you. Have you read 1 Corinthians 13 lately? Can people here read your conversations from others and get the impression that you are obeying 1 Corinthians 13? How about 1 John 3:15? For it says a believer who hates his brother is considered a murderer and does not have eternal life abiding in them. Can one hate another brother with their words? Is not mocking another believer being hateful?
I have no idea what your version of repentance is. But I know that the popular OSAS version of repentance is not true repentance according to the Bible. There are two different versions of OSAS repentance. The OSAS Lite version says you have to generally live a holy life and not live in sin. They say that if you do live in a life of sin, then you were never born again to begin with. But this makes one doubt the promises of God's grace that is shown to us 1 John 1:9 and Luke 18:9-14. For if we confess our sins, he is faithful and just to forgive us our sins. The popular version of repentance is that you simply have a change of mind and you do not have to turn from your wicked ways in order to be saved.
But Jesus defines repentance for us in the Bible, though. So one cannot twist what "repentance" actually means.
Jesus said the Ninevites will rise up in Judgement against this generation because they repented at the preaching of Jonah (Matthew 12:41). If you were to turn to Jonah chapter 3 and read the end of that chapter, you would learn that the Ninevites had departed from their wicked ways as a part of their repentance.
Not all sin is the same. Some sins lead to spiritual death and other sins DO lead to spiritual death. 1 John 5:16-18 talks about the sins that lead unto death and sins that do not lead unto death. Psalm 19:12 talks about the errors or faults that we do not know always know about. These are sins that do not lead unto death. For example: One is not going to be condemned to Hell if they refused to take out the trash last week like they knew they should have done. Sins unto death are sins that Paul lists several times in the New Testament. He creates a list of sins such as murder, hate, adultery, theft, drunkenness, and idolatry. He says be not deceived in regards to this matter. For they that do such things will not inherit the Kingdom of God. These are sins unto spiritual death. For John also lists these sins and says that doing these types of sins will lead unto the second DEATH which is the Lake of Fire.
Most sins can be forgiven if they are confessed; For if we confess our sins, he is faithful and just to forgive us our sin (1 John 1:9). But then we are to walk in the light as he is in the light, though. For if we walk in the light as he is in the light, then.... then.... the blood of Jesus Christ cleanses us from all sin (1 John 1:7).
No, James is talking about the sin of showing respect of persons (See James 2:1-9). James is not supporting the idea that it is okay to flat out disobey God and still continue to do wrong in showing favoritism. For James continues to say that if one does not have works (fruit from God in their life), then their faith is dead (James 2:17). In other words, one cannot have an empty profession of faith with no real results to prove their faith to be true. For he that does not love does not know God.
Also, James is speaking about the Law of Liberty and not the Law of Moses. See verse 12 (James 2:12). We have a liberty in Christ. We can eat unclean foods, whereas in the Law of Moses, this was not allowed. But we are not to let our good be evil spoken of, though. We are not to let our liberty in Christ on such matters be a bad thing. For surely a loving Christian would not eat unclean animals in front of others who thought it was offensive. For Christians are to love just as Christ loved.
