How do we know that redemption is sufficient?

In Psalm 130, we learn of plenteous redemption, which speaks to the abundance of Christ's sacrifice. His blood is described as precious and without blemish, fully capable of redeeming the elect. The sufficiency of redemption lies not in the number of sins we commit but in the infinite worth of Christ's offering. Thus, we can confidently trust that His atonement covers not just some, but all the sins of those whom He has chosen. This assurance gives believers continual hope in their struggle with sin.
