For Zeal

O almighty and merciful Father,
you pour out your benefits on us,
forgive our unthankfulness for your goodness.
We have stood before you with dead and senseless hearts,
unkindled by the love
of your gentle and enduring goodness.
O merciful Father, turn us and we will be turned.
Make us hunger and thirst for you with our whole heart,
and with all our longing desire you.
Make us serve you with our whole heart
and with all our zeal seek whatever is pleasing in your sight;
for the sake of your only Son,
to whom with you and the Holy Spirit be all honor and glory,
for ever and ever. Amen.
