Hardlyanybody has ever touched the truths of Romans 6 and 7, and therein lies the explanation of how to live that way. Be not ashamed, though, if you cannot say you understand clearly these chapters. Peter admitted the topic of righteousness that Paul delved into was hard to be understood. Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness. Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless.
Righteousness is a deep topic.
First of all, let us agree that the Bible is the source of information for believers that we may have victory over everything in life, as supplied by God through Christ's death on the cross. We have victory over sin, but, like the Romans, we may not know that . And if we do not know it, then we will not enjoy it. I want to make it clear that there is nothing else we need that we do not already have. There is nothing else to do and nothing else for God to do.
