People go through phases when faith just isn’t so important to them. They are on a different journey than you and you need to respect where they are at.
Middle aged people have a lot more responsibilities than a teenager. Honestly, it’s just hard to get “on fire” for anything when you are working and taking care of the kids, doing your daily stuff…making sure everyone and everything’s taken care of. It doesn’t mean that you don’t care about things. It means that faith is one of many important things, and sometimes, it will take a backseat to other priorities.
Also, teenagers are supposed to be more “on fire” than their parents. That’s why older people tend to envy the passion and vibrancy that young people have. Teenagers just haven’t been jaded by life in the “real world” and life’s responsibilities yet.
I know that my son gets excited about things that I just can’t imagine getting excited about at my age. I’ve been around the block. I know what the scoop is and it’s really not that exciting. (Some of the stuff, anyway) However, because he hasn’t experienced it before, it’s new and exciting and the most interesting thing that’s ever, ever happened. (I can’t wait to share more of those experiences w/him as he gets older.)
For instance, this year was the first year that my son got really into Christmas. (He just turned 5) If it had to do with Christmas, then he had to do it, have it, see it. It never got old for him. It was a major trauma when we put away the Christmas stuff because he loved the tree, the ornaments, the “bling”.
In a couple of years, I know he won’t be so excited about Christmas. It will still be a special time, but it will be different. He’ll be older. He’ll get that Christmas comes every year. And every year we put the tree and do this and that. It will still be fun, but not in the same way it is now.
Like someone said, don’t get judgmental. Pray.
I really won’t worry so much about it, unless they decide to go agnostic/atheist.
