In 1 Peter 1:17 NIV, it reads "Since you call on a Father Who judges each person's work impartially, live out your time as foreigners here in reverent fear.". Basically, once we claim to belong to God and are one of His children, we really should "act like our Father". There are some qualities that make up families. Some families are known for their cooking abilities. Others may be jokesters. Others may be artsy and do a lot of singing and dancing. Still others may be strict and proper everywhere they go. It's part of being in "that" particular family.
The same is true in the family of God. There are certain things we should be doing so that people know that we are in the family. There are certain activities we should be active participants - just because we call Him Daddy. Well, what does that look like? It's pretty well spelled out in what is called the "fruit of the Spirit" - love, joy, peace, longsuffering, gentleness, goodness, meekness, temperance. Those are the qualities that make up His Family.
So we have to consider, how are we doing in those areas? Do we really display the "family resemblance"? If not, we've got the opportunity to fix it today. It's a new day, let's start it off right so that someone will look at us and say "hey, you act just like your Daddy"
