Dealing with election and free will is difficult but important and enriching. So deal with it. Think about it. Read. Pray. Repeat. Good places to start... Ephesians 1, Romans 9, John 10, and our text from this past week; Matthew 11:25-30.
On another note, make sure you're remembering and reminding yourself this week that Jesus is your savior and that you don't need to work off any debt to the Father BECAUSE of what the Son accomplished!
