Children of God?

You are not your own, but you have been bought with a great price. He could choose to call us slaves or servants, but instead calls us friends, sisters and brothers.We bicker and fight with one another or non-essentials, when He has provided for every situationWe choose a life separated, but He is always near.We divide and conquer, but He brings together and loves.We are children of God? Shouldn't we act like it ?
