Best of Intentions

I want to be faithful to God. I want to go closer to him in prayer and obedience. I can’t do this in my own strength. This Sunday I stand before His people to speak about the parable of the persistent widow and the unjust judge (Lk 18:1-8). My questions – in what way am I like/ not like the widow? In what way is God like/ not like the judge? Is it saying I have to hammer on at God to get an answer? Why should this story encourage me to pray?
