We all have different ideas of worship. A simple prayer or a communion service with a scripture reading might be enough. Others may desire a sermon, or testimonies. Others find all of this tedious and would rather have intellectual stimulation that drives greater spiritual awareness.
The scriptures are full of examples of communities worshiping together in a variety of forms. The one thing these all have in common is the idea of the oneness with God in community. Life, and this includes spirituality, is not a journey to take alone. We must work to build the community of Saints that God has called us to be, His Zion.
Even in group settings, worship is personal. We should be open to the needs of all, and whatever the meeting type we should seek spiritual oneness in Christ. We are all capable of worshiping alone, yet God has told us to meet together (Matthew 18:20). Why? Because nothing grows in a vacuum.
