louie - keep on keeping on…
The reason for the shepherd’s rod and staff is to show the lambs which direction the good grass to feed on is. Sometimes - you gotta prod them along.
Are you forcing your faith on them? Haven’t they been going to church with you since they were wee little ones? They know it’s expected and it should be no surprise to them by now. Out of respect alone they should be able to give an hour on a Sunday to the good of the family and it is absolutely your job to do everything you can to help their souls along their faith journey.
Would you not feed them food for nourishment?
Don’t allow them to deny themselves the Bread of Life?
Once the move out…well all you can do is pray you have set the path and they continue to follow. Good luck.
