This doctrine manual deals specifically with biblical soteriology, the doctrine of salvation. It covers topics related to the work of Christ, from His life and fulfillment to the implications of His death on the cross. It explores the concepts of penal substitution, propitiation, reconciliation, the crucial point of Christ's mediation, the atoning sacrifice, His burial and resurrection, and how all of this connects with the message of the Gospel. It is an excellent manual for delving deeper into what the Bible says about how a just God can forgive unjust sinners; the key lies in Christ.
