*** w85 12/15 p. 7 How You Can Show Gratitude for What Jesus Did ***
Christian meetings are a way by which we can maintain proper esteem. Since Jehovah and Jesus are present invisibly at these gatherings, grateful Christians will not snub them, as the apostates do, but rather do all they reasonably can to attend regularly.
However, according to Watchtower doctrine, God is not omnipresent:
ka chap. 6 p. 98 par. 39 Priests for Ten Centuries with No Scheming Priestcraft
The Most High God has always had a place of residence in heaven. He is not an all-pervasive spirit that is omnipresent, present everywhere at the same time. Being an intelligent Person, he has his location, his place of residence where he can be approached.
This begs the question that since doctrine holds that Jehovah is NOT omnipresent, and Jesus is of course just a lowly angel who doesn't even have "holy spirit" at his disposal let alone omnipresence, how can it be said they are "present invisibly" at all the meetings? This simply shows that they make up this stuff as they go along.
