Every human being is born with an inbuilt desire to worship. Worship is the ultimate expression of a heart that is devoted to love, adore, serve and live for a deity. When it comes to the matter of which deity, a look around you tells that people differ in the matter of which deity is to be worshipped and how that deity is to be worshipped.
There are three noteworthy instances in the Bible where God rejected the worship offered to Him – one prior to the old covenant, one during the old covenant and one in the new covenant. It would do well to study these instances and glean lessons from them as to how we should not or we should worship our God and what kind of worship God would accept or reject and why.
