St. Thomas

And I totally love how this one is worded... it's just right. :)

Almighty and eternal God,
who, for the firmer foundation of our faith,
allowed your holy apostle Thomas
to doubt the resurrection of your Son
till word and sight convinced him:
grant to us, who have not seen, that we also may believe
and so confess Christ as our Lord and our God;
who is alive and reigns with you,
in the unity of the Holy Spirit,
one God, now and for ever.
