Teenagers are sometimes faced with challenging circumstances. When friends hang out, there are often different rules at each friend’s houses. Some parents have strict rules. Some parents are more lax and maybe have very few limits at all. So, where should they hang out? And, if there are no 
rules, then should “anything go” at those houses?
The reality is that teenagers are not the only ones faced with these situations. Every Christian, at some point or another, finds himself in a situation where there are no set boundaries on what he does. He (or she) could literally do anything and would not “get into any trouble for it.”
That’s when we need to remember “whose house we’re living in.” As Christians, we are in the family of God (Gal. 3:26-29), and we are always “in His house.” So, wherever we go and with whomever we happen to be “hanging,” our Father’s “rules” still apply. This is not to “cramp our style”! This is actually to simplify (and enhance) our lives (John 10:10; Deut. 6:24)!
