what is the best way to explain to unbelievers how catastrophes fit in with God? Are all catastrophes judgment?
In September 2001 I heard a great sermon on Amos 3:6 following the attack on the twin towers.
Amos 3:6 (ESV)
Is a trumpet blown in a city, and the people are not afraid?
Does disaster come to a city, unless the Lord has done it?
Romans 1:18, 19
18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men,
who by their unrighteousness suppress the truth.
19 For what can be known about God is plain to them,
because God has shown it to them.
One of the things that God has made plain to all men is that he is angry with mankind and manifests his anger by sending men more wicked to reveal his wrath. All men know this in their inmost being. They ask a question that they already know the answer to hoping that we Christians will aid them in their suppression of the truth. We must not do so. Tell them what they know. God is angry with fallen man.
Some people asked Jesus to explain the atrocity of Pilate against certain Galilaeans. He said in essence that these tragedies are a picture of what all men deserve. Meditate on his response in the verses below.
Luke 13:1-5
1 There were present at that season some that told him of the Galilaeans, whose blood Pilate had mingled with their sacrifices.
2 And Jesus answering said unto them, Suppose ye that these Galilaeans were sinners above all the Galilaeans, because they suffered such things?
3 I tell you, Nay: but, except ye repent, ye shall all likewise perish.
4 Or those eighteen, upon whom the tower in Siloam fell, and slew them, think ye that they were sinners above all men that dwelt in Jerusalem?
5 I tell you, Nay: but, except ye repent, ye shall all likewise perish.
PS - I do believe, as has been said above, that troubles come to Christians through the Lord's love and mercy.
