Jesus modeled prayer for His disciples when He prayed what we call “The Lord’s Prayer.” The disciples asked Jesus to teach them to pray as John had taught. While we don’t have record of John’s prayers, I can’t imagine anything better than following the prayer example of Jesus.
Matthew 6:9b-13 KJV
“Our Father which art in heaven, Hallowed be thy name.
Thy kingdom come, Thy will be done in earth, as it is in heaven.
Give us this day our daily bread.
And forgive us our debts, as we forgive our debtors.
And lead us not into temptation, but deliver us from evil:
For thine is the kingdom, and the power, and the glory, for ever. Amen.”
