Speaking at a tumultuous time and place (Roman rule).

Jesus was asked to teach his disciples to pray just as John (the Baptist) taught his followers (Luke 11:1).
How did John teach his disciples? I don't know.
Was it something liturgical like the Pharisees or other teachers of the time?

In response Jesus told his disciples to pray using the following framework (Luke 11:2-4).

Relationship Father.
Throne Room In Heaven.
Worship Honour and Reverence.
Repentance Your Kingdom ... Your will.
Provision Give us...
Forgiveness Handling hurts and disappointments.
Protection Keep us from...
Deliverance Deliver us from... (Matthew 6v13)
