Here is a prayer of dedication from the Giving in Grace website.
Prayer for the Offering
(inspired by scripture texts
like Philippians 4:19,
Matthew 6:25-34, Psalm
145:15-16)
Heavenly Father,
your love for us is beyond measure
and you provide for our every need.
Help us to offer you in worship a due
proportion of our wealth,
for all we are and have is rightly yours.
We make our prayer in the precious name of
Jesus,
Lord and Saviour of creation. Amen
