We're too busy for much more. Worship should be fast-paced. That goes for time between songs, silence between people on stage, and even the speed of music. Good worship needs good lighting. Now we have some pretty sophisticated lighting controls, and we're better off.
Faith comes by hearing.
We chuckle at our parent's style of worship with only one microphone attached to a wooden pulpit. The more mikes the merrier. Songs should be led by a group. This improved our worship in most places, or at least gave us something more attractive to look at while singing. Sometimes we added an orchestra of sorts to supply even more activity on the stage to keep us involved in worship.
