Collect

Merciful God, who sent thy messengers the prophets to
preach repentance and prepare the way for our salvation:
Give us grace to heed their warnings and forsake our sins,
that we may greet with joy the coming of Jesus Christ our
Redeemer; who liveth and reigneth with thee and the Holy
Spirit, one God, now and for ever. Amen.
