February 17, 2015. Extemporaneous Preaching Class at The General Theological Seminary. I was given 30 minutes of preparation time before delivering this sermon.

TEXT: Genesis 1:26-28

Then God said, ‘Let us make humankind in our image, according to our likeness; and let them have dominion over the fish of the sea, and over the birds of the air, and over the cattle, and over all the wild animals of the earth, and over every creeping thing that creeps upon the earth.’ 
So God created humankind in his image,
   in the image of God he created them;
   male and female he created them. 
God blessed them, and God said to them, ‘Be fruitful and multiply, and fill the earth and subdue it; and have dominion over the fish of the sea and over the birds of the air and over every living thing that moves upon the earth.’

I found that practicing extemporaneous preaching did not diminish the importance of research and preparation (which are highly important to me), but improved my pastoral presence and got me more comfortable with preaching without a full manuscript.
