What does 2 Peter 2:2 mean?
In the previous verse, Peter revealed that false teachers will rise up from within the community of Christians. These deceivers will use deception in an attempt to convince believers to deny Jesus as Lord and Master.One trait of these false teachers will be participation in immoral sexual conduct. This is something they will encourage Christians to join in, as well. Sadly, many in the church will follow their lead and do just that. In fact, Peter reveals that so many in the Christian church will join in these "depraved" or "sensual" practices that it will damage the reputation of the "way of truth." This is an all-too-familiar image of modern day cultures.
Many in the outside world, based on their experience of the Christians they know, will arrive at the conclusion that sexual immorality is normal for those who follow Jesus, harming the reputation of Christ Himself in the world.
For those of us in the church now, we have heard Peter warn us against two traits of false teachers. First is any teaching that would call into question Jesus' place as Lord. Second is any teaching from those who participate in sexual immorality, or suggest it is permissible for Christians to do so.
