There's a reason for our Heavenly Father's inaction too - Acts
There is no possible reason for god creating a world that kills millions of its inhabitants through earthquakes, volcanoes and tsunamis and then passively watching the carnage unfold.
If a man lays landmines around a village and watches children walk across the minefield he is guilty not only of a crime of omission for failing to call a warning but of a deliberate crime of commission.
Jesus claimed to have been sent to reveal the nature of his god and father. Not only does christianity claim that god is love, it defines the meaning of love, and explains the importance of love expressed as positive action in the interests of others.
I tell you, love your enemies and pray for those who persecute you, that you may be children of your Father in heaven. He causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous... Be perfect, therefore, as your heavenly Father is perfect. - Matt.5
Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? Matt.6
But love your enemies, do good to them, and lend to them without expecting to get anything back. Then your reward will be great, and you will be children of the Most High, because he is kind to the ungrateful and wicked. Be merciful, just as your Father is merciful. - Luke 6
Are not five sparrows sold for two pennies? Yet not one of them is forgotten by God. Indeed, the very hairs of your head are all numbered. Don’t be afraid; you are worth more than many sparrows. - Luke 12
Every good and perfect gift is from above, coming down from the Father of the heavenly lights, who does not change like shifting shadows. - Jas.1
"Love ... always protects" - 1 Cor.13
The god of Jesus is also a god who is active in the world. Millions of christians demonstrate their belief in an immanent god every day. When they thank god for their food or pray for protection for a loved one or for a new job or help with any one of a million concerns they confirm that they worship a god who acts in the real world.
Natural disasters are incompatible with other things that christians claim to know about god. All attempts to explain god's actions result in a story that is internally contradictory. The god of christian theism does not exist.
