Yes, I believe God ordains all that comes to pass (Eph 1:11) If a calamity occurs in a city has not the LORD done it?" (Amos 3:6). After losing all ten of his children after a great wind had caused the collapse of his son's house, Job says, "The LORD gave and the LORD has taken away. Blessed be the name of the LORD" (Job 1:21). After being covered with boils he says, "Shall we indeed accept good from God and not accept adversity?" (Job 2:10). Our world has been under judgment since the Fall, so there is sickness, death and calamity.
Jesus declared that disasters are reminders that we all live in our fallen world, of life's precariousness and ought to cause us all to repent:
(Quote) "...those eighteen on whom the tower in Siloam fell and killed them: do you think that they were worse offenders than all the others who lived in Jerusalem? No, I tell you; but unless you repent, you will all likewise perish.” (Luke 13:1–5)
Does this mean we (the church) should sit on our hands? No, I am thankful that God also ordains that his church would engage in acts of mercy and pray ... and that the prayers of His saints will play a role in, and affect the outcome of events and be instrumental in the salvation of souls. God ordains both the means and the ends.
"He directeth it under the whole heaven, and his lightning unto the ends of the earth...For he saith to the snow, Be thou on the earth; likewise to the small rain, and to the great rain of his strength...By the breath of God frost is given: and the breadth of the waters is straitened. Also by watering he wearieth the thick cloud: he scattereth his bright cloud: And it is turned round about by his counsels: that they may do whatsoever he commandeth them upon the face of the world in the earth. He causeth it to come, whether for correction, or for his land, or for mercy” (Job 37:3, 6, 10-13).
Lord, grant that, in the aftermath of these great hurricanes, that you would be feared, that water, food, medical supplies and other necessities would get to exactly where they need to go to meet critical needs ... and that you would send out your people into the midst of those suffering to care for them, to bring them mercy and to bear witness of their real need of the gospel. In the name of Christ our Lord, Amen.
