Why is the wrath of God a problem for the world?

According to John 3:18, those who do not believe in the name of God's one and only Son are already condemned. This condemnation is rooted in God's righteous judgment against sin, which ultimately reveals the weight of divine wrath. 2 Thessalonians 1:6-10 further elaborates on this by stating that God is just and will punish those who do not know Him and do not obey the gospel. The serious implication of this judgment underscores why many view Christ as problematic; He embodies the truth of God's holiness and justice, which threatens to expose the sin that people would rather keep hidden.
