Children of God be pure and righteous

1 John 3:1-9
How great is the love the Father has lavished on us, that we should be called children of God!
The reason the world does not know us is that it did not know him.
Everyone who has this hope in him purifies himself, just as he is pure.
He who does what is right is righteous, jut as he is righteous.
The reason the Son of God appeared was to destroy the devil's work.
No one who is born of God will continue to sin, because God's seed remains in him; he cannot go on sinning, because he has been born of God.
The child of God shares God's own nature. It is against that nature - out of character - to live a life of sin, to go on breaking God's law deliberately and habitually (the tenses of the verbs in the Greek make a distinction between this and the particular one-off sins referred to in 1:10)
Why?
When we are born of God, we will purifies ourselves and do the righteous as His is.
Everyone is sinner but God will erase our sins when we turn to Him, and God's seed remain in us, then we will know what is right and what is evil thing. We have the capability do the righteous and away from the evil. Conscious will remind us.
Erase the habitually sins should turn to the Lord, confess our sins and pray to the Lord help us away from sins.
How?
Away confess sins in me, Pray to the Lord forgive me and give me strength and spirit to get rid of sins. For I am children of God!
