Their problem, besides believing that it does, is that they also believe that the grace runs out and needs to be replenished constantly. Hence the need for always having to take communion on a regular basis.
Fortunately, Scripture tells the believer that God has LAVISHED His grace on us, not doled it out in stingy little parcels.
Ephesians 1:7-10 In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
These amateur apologists don't have a clue what God says about anything and obviously don't care what He says...They apparently are pagan in nature...
