How does God chastise us?

Have you ever heard the phrase "Acts of God"? It's used in insurance policies for extreme catastrophies. And have you ever heard someone say that "God sent this disease to teach me something" or "God let me experience this accident so I would be a better person"?
I guess you have heard all this and more about how God sends accidents, catastrophies, sickness and death to "teach His people something". But that is absolutely not true. God doesn't send any of these. He does not send bad things. We live in an evil world, and bad and evil things happen. In the Lord's prayer we pray: "Your will be done on earth as in heaven". Is there sickness and death in heaven? No. Do accidents happen in heaven? No. Why? Because God doesn't have any of these. He's not the author of accidents, sickness and catastrophies. He's the author of GOOD. He's a Good God.
God has, however, a way to chastise and teach His people, and that is through His Word. Let's look at a few verses of Scripture that show us this: "All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the man of God may be thoroughly equipped for every good work" (2 Timothy 3:16-17). Here it says that all Scripture is useful for teaching, rebuking, correcting and training in righteousness. Why is that so? So that the Christians may be thoroughly equipped for every good work! That means that if there's something wrong with me in the sense of me lacking something in my faith or I am doing something I shouldn't, THE WORD OF GOD is my teacher.
Paul also writes about this in 2 Corinthians, where he explains the result of a letter (= words) he sent to the church in Corinth. He says: "Even if I caused you sorrow by my letter, I do not regret it. Though I did regret it - I see that my letter hurt you, but only for a little while - yet now I am happy, not because you were made sorry, but because your sorrow led you to repentance. For you became sorrowful as God intended and so were not harmed in any way by us" (2 Corinthians 7:8-9). A situation in the church at Corinth needed to be addressed and corrected, and IF God's method of correction was sickness, death and accidents, Paul would have asked God to send this. But he did not do that. He sent A LETTER with words of caution. And the words he sent did their work; people repented and things were straightened out. The church was back on track again!
It's always God's Word that is the means God uses to chastise and correct us. Next time you hear someone say anything else, refuse to accept it. Sickness, death and accidents happen in this evil world, but they are not from God. And He does not use Satan's tools to teach His people. He uses His own tools, the Word to teach His people.
