Here is a great website to use to understand biblical passages better: http://blog.spu.edu/lectio/. This website is from Seattle Pacific University. The school of theology faculty have written commentary on all most all the book of the bible or will do at some point. This website is working through the whole bible. The faculty members write commentary. So this can be used as a guide when reading scripture for personal bible study or for preaching.
At First Presbyterian we are doing a sermon series on the Gospel of John. Currently the above mentioned website is also working through John right now. So I thought this would be a good resource for you all at FPC Vancouver!
