What is a Christian?
Do you understand yourself to have been a slave before you were a son? How is your sin nature still at war with the Spirit of God?
According to the sermon, you are a son if...? (if what?)
From Galatians 4:6-7, what does the Holy Spirit cause a child of God to do? Has the Spirit caused you to cry out, "Abba, Father?"
In what ways do you see the elemental spiritual forces of the world at play inside the church and outside the church? (e.g., think in terms of philosophies and ideas set up against the knowledge of God - Col 2:8, 2 Cor 10:5)
