OO focuses on 2 key prayers - The Lord's Prayer and The Serenity Prayer.

The Lord's Prayer - Jesus

Our Father, who art in heaven,
Hallowed be thy Name.
Thy kingdom come.
Thy will be done,
On earth as it is in heaven.
Give us this day our daily bread.
And forgive us our trespasses,
As we forgive those who trespass against us.
And lead us not into temptation,
But deliver us from evil.
For thine is the kingdom,
and the power,
and the glory,
for ever and ever.
Amen

The Serenity Prayer - Reinhold Neibuhr

God, grant me the Serenity
to accept the things I cannot change,
Courage to change the things I can,
and Wisdom to know the difference.

Living one day at a time,
enjoying one moment at a time,
accepting hardship as the pathway to peace.

Taking, as He did, this sinful world as it is,
not as I would have it.

Trusting that He will make all things right
if I surrender to His will.

That I may be reasonably happy in this life,
and supremely happy with Him forever in the next.

Amen
