John 6:63, Spiritual Worship - Worship in Truth - Words of Christ, Spirit and Life
It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life. Then Peter said thou hast the words of eternal life. If our worship depends upon the spirit of the speaker or that of the musical worship team to "sing idle songs and improvize upon the harp like David" then we are back under Law and there will never be any security. Rather, religionists will rebind the burdens upon the "Pack Animals" which Lord Jesus Christ died to remove.
