We can take great comfort in knowing that God is in charge and is aware of all that is happening in our world.
In Job 5, we are told that the Lord our God will come against all of the 'devices' of the wicked and that they will come to naught:
"He disappointeth the devices of the crafty, so that their hands cannot perform their enterprise. He taketh the wise in their own craftiness: and the counsel of the froward is carried headlong." Job 5:12-13
God will ultimately thwart the evil plans of the 'wicked' which are currently bringing famine, war, and destruction on the world. These are allowed to happen for a little while to expose their evil for which they will be 'without excuse'.
We can also take comfort that God is watching out for us through this time of great peril:
"In famine he shall redeem thee from death: and in war from the power of the sword. Thou shalt be hid from the scourge of the tongue: neither shalt thou be afraid of destruction when it cometh. At destruction and famine thou shalt laugh: neither shalt thou be afraid of the beasts of the earth." Job 5:20-22
