There are three kinds of worship in the New Testament. First , we read of ignorant worship. When Paul was in the midst of Mar's hill in Athens, he saw many idols around him. Those people worshiped ignorantly then. Many do the same today.
Millions bow down to idols and images.
Many millions more are following various religious practices out of ignorance of the Bible. Second , the Bible speaks of those whose worship is vain . The majority of people worship in this way today. They worship the Lord, it is true, but their worship is vain or void. Because it is according to the teachings and traditions of men.
