The Lord's Prayer
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,
the power, and the glory,
for ever and ever. Amen.
