We know redemption is true through Scripture, which affirms that we are bought with a price and that this was accomplished by Christ's blood.
The truth of redemption is grounded in the Scriptures. Passages like Romans 3:24 declare that we are justified freely by His grace through the redemption that is in Christ Jesus. Furthermore, 1 Peter 1:18-19 affirms that we were not redeemed with corruptible things, but with the precious blood of Christ. This reinforces the notion that the cost of our redemption signifies its truthfulness; our bondage to sin is broken, and we are assured of eternal redemption through faith in Him. Thus, our understanding of redemption comes from both the factual history of Christ's death and our personal experience of the transformative power of His redemption.
