And this is the truth, which we have heard for him
and announce to you,
that God is light
… and in him there is no darkness at all.

If we say that we have fellowship with him
yet we walk in darkness 
we are lying and we are not putting truth into practise. 

If we walk in the light
as he is in the light
we have fellowship with one another 
and the blood of Jesus his son cleanses us from all sin.

If we say that we do not have sin
we deceive ourselves and the truth is not in us.

If we confess our sins, he is faithful and just
so that he will forgive us our sins and cleanse from all unrighteousness.

If we say that we do not sin, we make him a liar and his word is not in us.

Grant, Lord,
that we may hold to you without parting,
worship you without wearying,
serve you without failing;
faithfully seek you,
happily find you,
and forever possess you,
the only God,blessed now and for ever.
Amen

St Anselm
