Meetings have always been bad.
If Paul had to "command" people to not forsake the gatherings, the meetings must have been really bad.
Considering that Jesus said in Matt 18:20 "For where there are two or three gathered together in my name, there I am in their midst.”"
And then in Matt 11:28-30: "Come to me, all you who are toiling and loaded down, and I will refresh you.
Take my yoke upon you and learn from me, for I am mild-temperedi and lowly in heart, and you will find refreshment for yourselves.
For my yoke is kindly, and my load is light.”
If people needed to be "commanded" to go to the meetings, that means they had forgotten that Jesus was at the meetings, or he wasn't there and his being there was not refreshing to them and his yoke kindly. That seems to be the case today, where Jesus just doesn't seem to be there if they are not refreshing, to where people would want to be there and they are not a light load.
