This is what we have heard from Jesus Christ,

and the message that we are announcing to you:

God is light; there is no darkness in him at all.

If we say that we are in union with God

while we are living in darkness,

we are lying because we are not living the truth.

But if we live our lives in the light,

as he is in the light,

we are in union with one another,

and the blood of Jesus, his Son,

purifies us from all sin.

If we say we have no sin in us,

we are deceiving ourselves

and refusing to admit the truth;

but if we acknowledge our sins,

then God who is faithful and just

will forgive our sins and purify us

from everything that is wrong.

To say that we have never sinned

is to call God a liar

and to show that his word is not in us.

I am writing this, my children,

to stop you sinning;

but if anyone should sin,

we have our advocate with the Father,

Jesus Christ, who is just;

he is the sacrifice that takes our sins away,

and not only ours,

but the whole world’s.
