4 We are writing to tell you these things, because this makes us truly happy.
5 Jesus told us God is light and doesn't have any darkness in him. Now we are telling you.
6 If we say we share in life with God and keep on living in the dark, we are lying and are not living by the truth.
7 But if we live in the light, as God does, we share in life with each other. And the blood of his Son Jesus washes all our sins away.
8 If we say we have not sinned, we are fooling ourselves, and the truth isn't in our hearts.
9 But if we confess our sins to God, he can always be trusted to forgive us and take our sins away.
10 If we say we have not sinned, we make God a liar, and his message isn't in our hearts.
