If you have children,, we're to train our children in the way they should go
Pro 22:6 So there will definitely be mixed messages to them.
If you go to church to worship, Ihere will be conflicts of interest.
If you believe in tithing/giving, they just might not want the money spent in that way.
You cant even talk with them about how a specific scripture is speaking to you, share how a pastor's message impacted you, etc. Time spent reading and studying Scripture when they want to be doing something with them or numerous things instead. Some spouses mock their believing partners.
So family values, time management, communication, and finances to name a few areas that would be influenced.
