Some possible topics for tonight:
1) Comparing and contrasting Peter and Paul and the vision they received and their response
2) 2 kingdoms clashing – whenever there is the work of God, you can expect the work of Satan close behind
3) Circumcision – the danger of imposing non-essential, external practices on others; the point is freedom in Christ
4) Disagreement between Paul and Barnabas regarding Mark – who was right?
