We are here in St Thomas's where William Battle invented his incision for taking out the appendix. I once was an RSO to a man who hated the McBurney incision but at the end of the argument people could still be friends. However, when it comes to the Gospel, more is at stake. It was because he thought that John Wesley was not taking Scripture seriously on certain points. There is nothing worse than a religious controversy for stirring the passions.
History is full of examples.
Fourthly, may God be thanked that we are not only redeemed but regenerate. We have not yet attained to the glory but God is working through his Spirit to make us fit for glory. It is not achieved passively or in a moment. We have to say 'No' to sin and actively do the right, but by God's grace, whatever our temperament or our genes, we can be moulded into a better pattern. Now we have laid a basic framework of how we need to be aware of our own strengths and weaknesses, we come on to the practicalities of how we actually cope.
