How do we know God protects us from sin?

The reassurance of God’s protection from sin lies in the truth that it is not our own strength or carefulness that saves us, but Christ's faithful keeping. The sermon emphasizes that while our enemies are many, our own strength is limited. However, we can find comfort and confidence in the promise of the Good Shepherd, who safeguards His flock. Hebrews 7:25 states that Christ is able to save completely those who come to God through Him, underscoring our reliance on His grace and power to resist sin and remain steadfast in our faith.
