Sarum Blessing

May the Lord direct our hearts,
this day and for ever,
in the love of God
and in the patient waiting for Christ.
The Lord bless us
and preserve us from all evil
and bring us to everlasting life;
through Jesus + Christ our Lord.
Amen.

God be in my head

God be in our heads, 
    and in our understanding.
God be in our eyes, 
    and in our looking;
God be in our mouths,
    and in our speaking;
God be in our heart,
    and in our thinking;
God be at our end,
    and at our departing.
