ANSWER: Yes, to satisfy his justice, God himself, out of mere mercy, reconciles us to himself and delivers us from sin and from the punishment for sin, by a Redeemer.
What is the justice of God? What would be some detrimental consequences to us and to the world if God did not insist on satisfying his justice?
Look carefully at the answer to this question. Who is the subject performing the actions of reconciling and delivering? Why is it significant that there is only one subject?
As you ponder the justice and mercy of God this week, you might enjoy a Puritan prayer called "The Mediator."
