And depending on the Christian one is listening to at the moment, his will can be revealed in contradictory and even mutually exclusive ways.It is the very essence of the belief in a God who has revealed His will to men.
And yet there are differences with in Christianity as to what constitutes a murder that God prohibits. Even that is a hair that has been split in the name of God. Some Christians choose to believe abortion is murder, others do not, some Christians believe capital punishment to be murder, while others do not.I can confidently express the view that God prohibits murder. Why? Because He has clearly revealed that aspect of His will for us.
But what constitutes idol worship and what does not has long been the subject of differences of opinion in Christianity.I can say confidently that idol worship is contrary to God's will for us for the same reason.
What part of the concept of omnipotence aren't you grasping? He is God, He can darn well do what He wants. You may not like it, but God has always been a bit fickle.If you tell me that God has revealed to you that you may commit adultery, I can confidently conclude that you are a liar or you are mistaken, because the very nature of God precludes His having revealed that to you.
The same can be said of your choice of beliefs too, or hadn't you thought of that. God decides who has gotten the whole Christianity thingy right, not His Christians.You can start a religion based on the belief in the moral correctness of adultery. You can gain voting control over a previously Christian denomination and make that change to its tenets but having done so, it does not follow that God calls you to that position or that your beliefs remain Christian.
