Mariner's Church, http://www.marinerschurch.org, is located in Irvine, California, and they offer complete sermon series as both audio and video podcasts; I've only listened to the audio. The first I listened to, "Ruth - The Romance of Redemption" is a seven-part series, each sermon being roughly 30 to 45 in length. The pastor, an associate pastor, and the pastor's father--who is also the pastor of a California church, deliver their messages with a thoroughness of exposition that hardly leaves a stone unturned. The doctrine is sound, so I was a little surprised to hear the pastor announce that his 81 year old father would preach one of the sermons, "The Revelation of Ruth", in which he interprets The Book of the Revelation of Jesus Christ in light of the book of Ruth. Needless to say, I listened intently as he did just that! The preaching of all three, especially the pastor, featured interaction with the congregation that made me focus on every word and every thought, for the preacher would often have those in attendance verbally fill in blanks in the message, which they did with little prompting required. So far, I give this podcast the highest marks for being worthy of listening.
