What does the Bible say about inner corruption?

Scripture emphasizes the importance of acknowledging and confronting our inner corruption. In Numbers 5, the Israelites were instructed to deal with external indicators of inner corruption, such as leprosy and bodily issues. This reflects the deeper reality that all humans must confront their innate sinfulness. As stated in Romans 7:18, 'For I know that in me (that is, in my flesh) dwells no good thing.' Acknowledging our depravity aligns with the gospel’s message of reliance on Christ for redemption, and it is essential for spiritual growth.
