Christian Worship is primarily about worshipping God for who He is and what He has done for sinners like us. If it is entirely about Him, then we are to worship in a way that God prescribes and instructs. The Holy Spirit enables us to worship God in a way that is acceptable to Him.
God often gently convicts His people of their sinfulness and rebelliousness even when the sins of His people might seem like an insignificant sin, lest such a sin grow into fruition. But when a nation commits idolatry, God also does not withhold from punishing and rebuking them. In this passage, we learn how to avoid being in opposition or hostile to God and His ways in our daily lives.
