I have no problem with that but I don't really see anyone pointing to anything wrong Fred is doing, rather, they are saying he doesn't seem to act devoted enough to be as good a Christian as they are.
True that. Those without sin may cast the first stone. Not saying that not attending church is a sin because it isn’t a sin. It is good to go for encouragement being around other Christian people and being there to hear the word of the Lord. Church is not a building but a gathering of God’s people coming together to worship. How can these people call out Fred for not attending church when they don’t themselves. They should say Fred as well as myself don’t attend and it would be good for us if we did.
