Christ’s death enabled God’s grace.
Sinners are justified through both Christ’s death and God’s grace. If Christ did not “overcome” (Rev 3:21), we would all have been eternally lost. However, Christ’s death alone is insufficient: Faith and grace are also required for salvation. Romans 3:25-26 explains that Christ’s death demonstrated that it is just of God to justify sinners by faith alone, which is judgment by grace.
