DTD:
In English the noun “will” means ‘desire, wish, determination, something desired, especially a choice or determination of one having authority or power.’
The Hebrew word for “will” carries the thoughts ‘delight, desire, favor, or pleasure.’
The disasters that happen, tsunamis, earthquake, floods etc. are not God's Will. That is a phrase put out by man, especially clergy who have no answers. when asked as to why these things occur.
The disciple James, wrote: “When under trial, let no one say: ‘I am being tried by God.’ For with evil things God cannot be tried nor does he himself try anyone.” (James 1:13) God is not the source of what is bad. Plainly, therefore, not all that happens on earth today is God’s will.
It is man's fault. Many times warnings are given by those in authority but do the general public obey them? No, so when disasters happen and thousands are killed in many (not all) instances it happened through disobedience. For example, if I saw a small fire near your house and warned you about it, you laughed and said it would not reach your house and it did. The result being that your house burned down and maybe killed or injured members of your family - is it God's will or just your own stupidity for ignoring the warning?
