How do we know God delivers us from sin?

The assurance of God's deliverance from sin is found in His promises throughout Scripture. Ephesians 2:8-9 emphasizes that we are saved by grace through faith, not of ourselves; this is the gift of God. This salvation leads to good works that God has prepared for us to walk in (Ephesians 2:10), affirming that a life changed by Christ is evidence of true deliverance. When we see the flesh weakened by temptation yet find strength in Christ to overcome, we can be confident in His saving work.
