One of the primary reasons why we are saved through the Lord Jesus is to serve God who is his father in heaven. In order to serve God, you must be faithful. If you must serve God then you can't disobey God's authority. This was the same manner Christ walked in when he was on earth. To disobey God's authority is to walk with the principle of Satan.
John 4:23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him.
It sad that many believers don't know the implications of disobeying God's authority. In today's Christianity, there are many people who stand with God in doctrine but are still observing the principle of the devil unknowingly.
James 4:7 Submit yourselves therefore to God. Resist the devil, and he will flee from you.
Whatever service you are rendering to God is in vain as long as you are standing with the devil's principle. You must first submit to God before you can resist the devil
