Reasons for Divine Judgment

People are very uncomfortable talking about God's judgment. While it's not "fun" to talk about, to avoid it is to minimize the words of God revealed to us. In plain language, God condemns sinners to show His glory. The severity of hell is to show with clarity the worth of His name. To the degree we minimize hell and judgment, to that degree we make little of God's majesty and beauty.

Hell is as awful as it is because God is as awesome as He is.

Listen to Psalm 83: 16-18,

Fill their faces with shame,
that they may seek your name, O Lord.

Let them be put to shame and dismayed forever;
let them perish in disgrace,

that they may know that you alone,
whose name is the Lord,
are the Most High over all the earth.

Also, see Romans 9:21-23,

21 Has the potter no right over the clay, to make out of the same lump one vessel for honorable use and another for dishonorable use? 22 What if God, desiring to show his wrath and to make known his power, has endured with much patience vessels of wrath prepared for destruction, 23 in order to make known the riches of his glory for vessels of mercy, which he has prepared beforehand for glory—

Or see 2 Thessalonians 1:5-10,

This is evidence of the righteous judgment of God, that you may be considered worthy of the kingdom of God, for which you are also suffering— 6 since indeed God considers it just to repay with affliction those who afflict you, 7 and to grant relief to you who are afflicted as well as to us, when the Lord Jesus is revealed from heaven with his mighty angels 8 in flaming fire, inflicting vengeance on those who do not know God and on those who do not obey the gospel of our Lord Jesus. 9 They will suffer the punishment of eternal destruction that comes from the presence of the Lord and from the glory of his might, 10 when he comes on that day to be glorified in his saints, and to be marveled at among all who have believed, because our testimony to you was believed.
