Philippians 2:10-11 - That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father.
Revelation 14:10 - The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
How is God glorified in the destruction of the wicked? It shows that He is God and He is sovereign. The wicked hate Him and wish He's not there. Even when it's not yet Judgment Day but one can see that God is glorified when the wicked are destroyed. Many tried to disprove God only to make fools out of themselves and died Christless deaths. No one can deny that God's Word is true whether you agree with it or not. If you refuse to glorify God by accepting and applying His Word as truth then you're going to end up glorifying God through your damnation.
One good example of God getting the glory in the destruction of the wicked was the destruction of Herod Agrippa. Here's what the Bible says:
Acts 12:22-24 - And upon a set day Herod, arrayed in royal apparel, sat upon his throne, and made an oration unto them. And the people gave a shout, saying, It is the voice of a god, and not of a man. And immediately the angel of the Lord smote him, because he gave not God the glory: and he was eaten of worms, and gave up the ghost. But the Word of God grew and multiplied.
The problem of Herod Agrippa here was that after he usurped his half-uncle Herod Antipas' throne, he decided to grab the glory for himself. Just think that after he decided to give not God the glory, God was still glorified in his destruction. According to Josephus, he actually died from some kind of gangrene which lasted for five straight days. I can't imagine how the pain must be for that wicked man. Whether or not he repented the Scripture is silent but I assume he didn't. What happened next was that in the midst of God-haters, the Word of God still grew and multiplied. God was still glorified in the destruction of Herod Agrippa. The same went for many godless rules who tried to suppress His Word got destroyed and God was still glorified in their rejection of Him.
When people refuse to give the glory to God in their salvation then they'll give glory when they're already in eternal damnation. They'll end up giving the glory when it's too late. There will come a time when even the worst people will bow down and say, "JESUS CHRIST IS LORD" but it's too late. Even Satan the evil one will will say, "Jesus is Lord." at the end of age at the terror that he's defeated. But it's too late for the damned to say Jesus is Lord because they're already damned (Hebrews 9:27).
When do you want to declare Jesus is Lord? Now or later? I urge you if you're not saved to please receive Jesus as your Lord and Savior before it's too late! Otherwise, it'd be too late and you're going to end up in the Lake of Fire for all eternity.
