9 Those born from God don’t practice sin because God’s DNA remains in them. They can’t sin because they are born from God. 10 This is how God’s children and the devil’s children are apparent: everyone who doesn’t practice righteousness is not from God, including the person who doesn’t love a brother or sister.
1 John 3:9-10, CEB
If you are a child of God you can’t sin. If you’re a child of your shouldn’t practice sinning. So, how do you convince a Christian to sin? You make them forget their true identity. It’s that simple, really.
