Biblically, the God who fashioned men also fashioned ants, lions, penguins, and gypsy moths. so God is the God of all of His creatures, of all creation, as God is the Creator not just of men, but of all living things.
all living things rely on Him for care, sustainance, and breath.
Greatest, i've already answered your question in number of ways as to God's standards for us, versus what God Himself is able / capable of doing of His own will.
you are right in saying that man has his own laws- human societies have many laws and commandments which have nothing to do with what God has asked of us. God is not a man, and is not liable to make those errors of judgement, or foresight which we humans can and often do make. His nature dictates that He does not sin, nor does He do evil. might God bring about suffering and destruction to mould His cause and plan? yes. does that mean that God has done evil? Biblically, by no means.
is this something you may simply not be able to understand or accept? perhaps. but the Biblical world view and understanding of God's natue makes some basic statements and stands on some basic assumed truths. to deny or reject those truths, is to reject the Bible, and to reject the God it describes. to do so, is to reject His Son, the Messiah, whom Christians identify as Jesus Christ. no one can compell faith, G. no one can compell discipleship, either.
there are many who will try to enter that narror door, and fail. and there are many ways which seem right to men, but which do not lead to the truth.
