Todd Friel addresses the importance of assurance in salvation, explaining that doubts are not from God but from the devil, who deceives Christians into questioning their salvation. He identifies common lies, such as focusing too much on sin, needing 100% assurance, and misunderstanding life circumstances or struggles with sin, and counters them with biblical truths, emphasizing that struggles and doubts don’t disqualify someone from salvation. Friel concludes by encouraging Christians to focus on God’s promises and the evidence of their faith, finding assurance in their relationship with Christ rather than fleeting emotions or circumstances.
