Here are my thoughts to prepare the talk:
This is a very interesting issue, because it seems for me many years incompatible to believe in God and in evolution. Long time of my life I couldn`t imagine that evolution was possible, although I know many good Christians who believe in God and evolution. Some of them are good friends and I accept their thinking. So I started a journey and in the last two years I found a way to bring both approaches a little bit closer together.
I’m still on the way with this issue. I see three different ways to handle it, some with various forms:
1. Creation is right – evolution is wrong and just a theory
1a. Creation ist right – the biblical report ist true and complete.
1b. Creation is right – but indeed there is a way of micro-evolution (within the species) (currently my opinion)
2. Evolution is right – Creation is wrong
2a. Creation is just a good story – there is no God. God is dead.
2b. There must be somebody who started the evolution and give the first information to start (maybe a God)
2c. The nature is so great and complex – there must be a designer (intelligent design), maybe a God
3. God create the world through evolution
The Story about creation in Genesis shows us the fact, that God has created us. It tells us about the problem of sin. It’s a story. And we must read it in a different way and like a true story with important truths, but not as an exact report about the process of creation. It was written in a pattern, that everyone at any time could find the important facts about life . So Christians are not silly. They say we need an answer because of sin, war, accidents, love, identity, good and evil and the bible tells us, that God is the creator and inventor of life and give us a good instruction for life. And later on the bible shows us Jesus Christ, who is the savior and the answer (recently I sympathies with this opinion).
Maybe there are some more ways.
Here I found a good article about the issue: http://www.eauk.org/church/resources/theological-articles/can-a-christian-believe-in-evolution.cfm
Also I found this Christian evangelical website: http://www.cis.org.uk/
And here is an new book by John Lennox about creation: Sieben Tage, das Universum und Gott.
