Your children will be about one step further away from Jesus than you are while raising them.
Let that sink in.
If you go to Church twice a month, then your children will probably be attending once every couple of months. If you serve others in the name of Jesus once a month, they will probably serve a couple of times a year. If you do not read your Bible except on Sunday, they will not read it at all. If you are only generous to the people who give to you, your children will be selfish.
The best way to help your children be fully devoted followers of Jesus is to be one yourself. Their life will be a slightly distorted reflection of yours.
