How do we know that redemption is accomplished by Christ?

The certainty of redemption being accomplished by Christ lies in the fulfillment of prophecy and the New Testament's clear teaching. As the Apostle Paul notes, 'For while we were still weak, at the right time Christ died for the ungodly' (Romans 5:6). This indicates that Jesus' life and sacrificial death were preordained for our salvation. Furthermore, Hebrews 9:12 states, 'He entered once for all into the holy places, not by means of the blood of goats and calves but by means of His own blood, thus securing an eternal redemption.' Through His death, Jesus doesn't just serve as an example but rather as the perfect, spotless Lamb whose sacrifice removes our transgressions and reconciles us to God. Therefore, the completed work of Christ is foundational to the doctrine of redemption.
