Pray then like this: 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 debts, as we also have forgiven our debtors; lead us not into temptation, but deliver us from evil. For Thine is the kingdom and the power and the glory forever and ever. Amen.

His peace will keep your thoughts and your hearts quiet and at rest as you trust in Christ Jesus.
