How do we know God's judgment is righteous?

In the Christian understanding, God's judgment is intrinsically righteous because it operates from His perfect nature and wisdom. As articulated in the sermon, those who believe God's record and obey His gospel demonstrate the faith that God has bestowed upon them. This faith is what qualifies believers as worthy of the kingdom, as their righteousness is not of their own doing but rather a result of Christ's work and the grace imparted to them. This understanding can be found throughout scripture, including Galatians 3:6, where belief is accounted for righteousness.
