How do we know that Christ's death protects us from condemnation?

The assurance that believers are not condemned comes directly from the fact that Christ died for our sins. Romans 8:34 states that it is Christ who died and is now interceding for us. This intercession means that when God looks upon those who are in Christ, He sees the righteousness of Christ, not our sinful past. Christ, being fully God and fully man, was able to bear the weight of sin and, in doing so, satisfied divine justice. Thus, through His death and resurrection, believers can claim security from condemnation because their guilt has been removed.
