How do we know God can be just and justify sinners?

The sermon underscores the essential theological question of how God can be both just and the justifier of sinners. This paradox is exemplified in the narrative of Daniel and the Lion's Den, which presents God as a righteous judge who upholds His law while simultaneously providing a means of salvation for His people. Daniel's deliverance from the lions points to the ultimate deliverance found in Christ, our substitute, who was also unjustly condemned. It illustrates that through Christ's sacrifice, God can justifiably forgive sins without compromising His holiness, fulfilling both His justice and mercy simultaneously.
