Why is it important for Christians to understand God's justice alongside His mercy?

The harmony of God's mercy and justice is a vital aspect of Christian doctrine. In Psalm 85, mercy and truth come together, highlighting how God's justice demands a payment for sin while His mercy offers forgiveness. God does not overlook sin but instead satisfies His justice through the sacrifice of Jesus Christ, who bore our sins and incurred God's wrath on our behalf. This profound truth is central to understanding the nature of the gospel and fully appreciating what Christ accomplished at Calvary, where mercy and justice meet perfectly.
