Public worship is just as important as private worship.
It is so important that Christ Himself gives the promise of His special presence and blessing only to public worship. Where two or three are gathered together in My name, there am I in the midst of them. One who does not worship God publicly in reality does not worship God privately either. If a person can willingly and habitually absent themselves from public worship, one of two things is true. They are in a serious, spiritually sick condition.
