Christians are called to fight sin. Sin is what Jesus died to save lots of us from. Sin separates us from a relationship with God, in addition to one another. The power of Jesus’ resurrection is that sin now not enslaves us. God has empowered us by his Spirit to fight back against it.
For essentially the most part, Christians have a broad agreement about what constitutes as “sin.” For example, violence, rage, greed, lust, lying, and theft are all things that Christians almost universally agree are unequivocally fallacious.
Nevertheless, there are numerous other practices where less agreement exists. In some instances, scriptural support for a given motion being a “sin” could also be scant, but it surely appears to be related to or approaching other sins where we do have clear scriptural instruction.
In these instances, Christians are called to exercise wisdom — to stay above reproach and never unnecessarily put ourselves able to be tempted. Read more here.
