We’ve been in John for about 1 1/2 years meeting once a week for an hour. We really try to exposit the scripture. It took us about 3 months to finish shapter 15!
I thought we were slow; three months to cover one chapter, now that's impressive!
John 15 has one of my favorite lines of scripture:
I no longer call you servants, because a servant does not know his master's business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you.
