1 John 1:7-10

But when we live in a right way, it is like living in the light. God is always in the light. So, if we live in the light, we share together in the life which God gives. And when Jesus, the Son of God, died on the cross, he saved us from all our sins. The blood of his sacrifice makes us clean. If we say that we never do any wrong thing, we are deceiving ourselves. Even though we may think it is true, it is a lie. Instead, we should agree that we have done wrong things and tell that to God. Then God will forgive us for our sins. He always does what he has promised to do. He always does what is right. He will forgive us and he will make us clean again, whatever bad things we may have done. God says that all people have done wrong things. So, if we say that we have not done any wrong thing, we are saying that God tells lies. It shows that we have not accepted his message at all.
