A Church worshipping as a Creature of the Word doesn't show up to perform or be entertained; she comes desperate and needy, thirsty for grace, receiving from The Lord and the body of Christ, and then gratefully receiving what she needs as she offers her praise- the only proper response to the God who saves us.
The bread that you see on the altar is the Body of Christ as soon as it is sanctified by God's word. The chalice, or better what is contained in the chalice, is the Blood of Christ as soon as it is sanctified by God's word
For generations, the body of Christ has been defeated and put under a constant siege of condemnation from the accuser because they believe wrongly that the Holy Spirit convicts believers of their sins.
