Instead of being just another person giving my opinion on the subject, let me give you what the Bible says and encourage you to think for yourself and believe the Word of God.
Does God punish sinners?
“From the Lord of hosts you will be punished with thunder and earthquake and loud noise” (Isaiah 29:6)
Then there came flashes of lightning, rumblings, peals of thunder and a severe earthquake. No earthquake like it has ever occurred since man has been on earth, so tremendous was the quake. The great city split into three parts, and the cities of the nations collapsed. God remembered Babylon the Great and gave her the cup filled with the wine of the fury of his wrath. (Revelation 16:18-19)
This is what the LORD says about this people: “They greatly love to wander; they do not restrain their feet. So the LORD does not accept them; he will now remember their wickedness and punish them for their sins.” Then the LORD said to me, “Do not pray for the well-being of this people. Although they fast, I will not listen to their cry; though they offer burnt offerings and grain offerings, I will not accept them. Instead, I will destroy them with the sword, famine and plague.” (Jeremiah 14:10-12)
…The Lord knows how to rescue the godly from temptation, and to keep the unrighteous under punishment for the day of judgment (2 Peter 2:9, see verses 4-9)
Does God send earthquakes?
Isaiah 29:6, Revelation16:18-19: quoted above
Then panic struck the whole army—those in the camp and field, and those in the outposts and raiding parties—and the ground shook. It was a panic sent by God. (1 Samuel 14:15)
Therefore the LORD’s anger burns against his people; his hand is raised and he strikes them down. The mountains shake, and the dead bodies are like refuse in the streets. Yet for all this, his anger is not turned away, his hand is still upraised. (Isaiah 5:25)
And behold, the veil of the temple was torn in two from top to bottom; and the earth shook and the rocks were split. The tombs were opened, and many bodies of the saints who had fallen asleep were raised; and coming out of the tombs after His resurrection they entered the holy city and appeared to many. Now the centurion, and those who were with him keeping guard over Jesus, when they saw the earthquake and the things that were happening, became very frightened and said, “Truly this was the Son of God!” (Matthew 27:51-54)
After they prayed, the place where they were meeting was shaken. And they were all filled with the Holy Spirit and spoke the word of God boldly. (Acts 4:31)
About midnight Paul and Silas were praying and singing hymns to God, and the other prisoners were listening to them. Suddenly there was such a violent earthquake that the foundations of the prison were shaken. At once all the prison doors flew open, and everybody’s chains came loose. (Acts 16:25-26)
Or do you suppose that those eighteen on whom the tower in Siloam fell and killed them were worse culprits than all the men who live in Jerusalem? “I tell you, no, but unless you repent, you will all likewise perish.” (Luke 13:4-5)
Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires and greed, which is idolatry. For it is because of these things that the wrath of God will come upon the sons of disobedience (Colossians 3:5-6)
The earthquake in Haiti showed God’s love. In His love He is just. His wrath was poured out as punishment for the disobedient. In His love He was merciful and spared the majority, giving them a chance to repent and be with the God who loves them.
Christians saying God wasn’t behind the earthquake are not showing love to the Haitians. If there is no wrath,there is no fear of God. If there is no fear of God, there is not even the beginning of wisdom or knowledge or hatred of evil. (Psalm 111:10, Proverbs 1:7, Proverbs 8:13) So without the fear of the Lord, how can there be salvation?
God is love. Since the days of Noah, God has spared most of the world, a disobedient world storing up wrath for itself. (Romans 2:5-8) But a day will come when no one will escape who isn’t hidden in the secret place. (Revelation 6:12-17, 2 Peter 3:7)
Where is the secret place?
He who dwells in the shelter of the Most High will rest in the shadow of the Almighty. I will say of the LORD, “He is my refuge and my fortress, my God, in whom I trust.” Surely he will save you from the fowler’s snare and from the deadly pestilence. He will cover you with his feathers, and under his wings you will find refuge; his faithfulness will be your shield and rampart. You will not fear the terror of night, nor the arrow that flies by day, nor the pestilence that stalks in the darkness, nor the plague that destroys at midday. A thousand may fall at your side, ten thousand at your right hand, but it will not come near you. You will only observe with your eyes and see the punishment of the wicked. If you make the Most High your dwelling— even the LORD, who is my refuge- then no harm will befall you, no disaster will come near your tent. For he will command his angels concerning you to guard you in all your ways; they will lift you up in their hands, so that you will not strike your foot against a stone. You will tread upon the lion and the cobra; you will trample the great lion and the serpent. “Because he loves me,” says the LORD, “I will rescue him; I will protect him, for he acknowledges my name. He will call upon me, and I will answer him; I will be with him in trouble, I will deliver him and honor him. With long life will I satisfy him and show him my salvation.”
Verse 14 says that we will be protected and rescued if we love God. And who is the one who loves God? “He who has My commandments and keeps them is the one who loves me…” (John 14:21)
