In this episode of Prove All Things, Jeff and Mike visit with Bill Jacobs to unpack a powerful question: Are people born sinful, or does sin take root through influence and choice? Drawing from counseling experience and Scripture, Bill contrasts common “original sin” assumptions with a biblical picture of sin as something that tries to enter and spread—like a foothold that grows into a stronghold. The group discusses trauma, addiction, and how repeated experiences shape thinking, then pivots to the hope of transformation as we “set our minds on the things above” and walk by the Spirit. This is a thoughtful, practical conversation about how real change happens—and how Christ helps us fight the battle in the heart.
