As I am finishing up my morning prayer time I am reminded of a out line that I have used over the years to help me pray.  ACTS

Acknowledge. Who God is in our lives.
Confess our sins before Him
Thanksgiving  thanking Him for who He is and what He has done
Supplication asking God for specific things.

Forgiveness is the hardest command in the Word of God to deal with revenge can be sweet.  Yet we are commanded to forgive which is a choice. This choice depended on our attitude and willingness to change. Then allowing the Holy Spirit to do the rest.
