What does the Bible say about fleshly lust?

According to 1 Peter 2:11, believers are exhorted to abstain from fleshly lusts which war against the soul. This concept emphasizes that lust refers not only to sexual sin but encompasses any sinful desire originating from our corrupted nature. The destructive nature of these desires is highlighted in the context of spiritual warfare, indicating that they hinder our relationship with God. In contrast, believers possess a new heart and spirit through regeneration, empowering them to resist such lusts and pursue righteousness instead.
