How do we know Christ's death redeems us?

The certainty of our redemption through Christ's death is rooted in the truth of His sacrificial atonement. According to Scripture, Jesus became the substitute for sinners, taking upon Himself the penalty that we rightfully deserved. His blood was the redemptive price paid to free us from sin's bondage, as articulated in passages like 1 Peter 1:18-19, emphasizing we were redeemed not with perishable things but with the precious blood of Christ. The effectiveness of this redemption is assured because He accomplished what the law could not—fulfilling the requirement of righteousness while offering Himself as the perfect sacrifice. Thus, the assurance of our redemption grounds us in faith that, through Christ, we are fully forgiven and liberated from all sin.
