1 John 3:9-10
9-10People conceived and brought into life by God don't make a practice of sin. How could they? God's seed is deep within them, making them who they are. It's not in the nature of the God-begotten to practice and parade sin. Here's how you tell the difference between God's children and the Devil's children: The one who won't practice righteous ways isn't from God, nor is the one who won't love brother or sister. A simple test.
11For this is the original message we heard: We should love each other.
