This episode reemphasizes the futility of a sin-focused life apart from serving God. Such a misplaced focus explains why many apparently plateau in their Christianity and why most Christians are "unemployed" Christians. While Christians definitely should address issues of sin, the focus of the Christian life is on Christ, abiding in Him, and implementing His instructions. Service to God is the reason God saved us.
Another casualty of sin-obsession: love of neighbor
This episode builds on the last two, in which a misplaced focus on sin distorts the central purpose of salvation, which is to serve the living God. In addition to rehashing the consequences of this misplaced focus, whether one apparently gets the victory over sin or not, this episode addresses how this approach undermines love of neighbor. Being sin-focused and not God-focused gets projected on one's neighbor, potentially leading to a judgmental attitude towards neighbor because the primary lens for the self-absorbed Christian has become victory over sin. A service orientation towards God is much more conducive to love of neighbor.
