O Lord Jesus Christ,
our redemption and our salvation,
we praise you and give you thanks.
Though we are unworthy of your benefits,
and cannot offer to you the devotion you deserve,
let your loving-kindness complete whatever our weakness tries to do.
Before you, O Lord, we lay all our desires,
and whatever our heart rightly wishes, it is because of your gift.
Help us love you as you command.
Do not let your gift be unfruitful in us.
Complete what you have begun,
give what you have made us desire,
convert our lukewarmness into fervent love of you;
for the glory of your holy name. Amen.
