"how do you control what your son or daughter sees on the screen?"
Be a parent:
- Raise your children as Christians.
- Teach your children about the world and its sinful influences.
- Recognize that entertainment is of a sinful world and has sinful influences.
- Stop sinful influences in your household.
- Remove TV completely.
- Cancel subscriptions to streaming services.
- Use the parental tools available on internet streaming websites like YouTube.
- Limit and supervise your child's access to the internet.
- Take away smart devices from your kids. Kids do not need smartphones, nor do they need tablets.
As parents, you are in control of what your children consume on a daily basis.
I have a friend who idolizes Dragonball Z and comic superheroes. He's a 50 year old man who fantasizes about these things being real. These sorts of things become like a god to many, which is idolatry.
Have no other gods before Him. Exodus 20:1-3
Do not bow down and worship any thing on this earth. Exodus 20:4-6
Love not the world. 1 John 2:15
