Luke 18:1-8 - Jesus tells of a parable about praying not giving up; concluding, 'will he find faith on the earth?'
After Jesus was crucified and resurrected he could have gone home to the Father but chose to remain with his friends again
Enter the scene on the road to Emmaus
He wanted to know their hearts. Where was their faith? - They still did not get it
He did not walk away in disgust and give up on them
He waited to see if their faith would revive
