Pastor Yuri Shibaev
Yuri Shibaev grew up in a family of unbelieving parents in Bryansk, Russia. He had heard about God from his grandmother when he was seven years old, but it wasn’t until he began studying the Bible that he made a profession of faith in 1991, at the age of twenty-four.
He has assisted FaithSearch Russian evangelist Oleg Voskresensky many times on his trips to Russia, and is now a part-time associate evangelist with FaithSearch, serving in Bryansk.
Tim Maki – Northland
Tim Maki has been involved in evangelism and church multiplication for most of his ministry. He is pastor of North Star Church in Hibbing, Minnesota, a church he began seven years ago.
He has known Dr. Don since September of 1983, while he attended St. Paul Bible College (now Crown College). In Dr. Bierle’s “Introduction to Christian Ministries” course, he was exposed to much of the teaching which is now FaithSearch Discovery. Over the years he has been trained to teach the FaithSearch Discovery presentation, and has used it in ministry as a church planter and pastor. He said, “With the growing percent of the millennial generation rejecting God, faith, and the established church, there has, in my estimation, never been a more prime time to use the Gospel with evidence as a main tool in both presenting the Good News and equipping the church to be able to give a reason for the hope they have!”
As part of his process of transition out of the pastorate and back into a role as an evangelist and church plant catalyst, Tim has formed a new ministry called North Star Ministries.
Concurrent with this, Tim has taken on the role of FaithSearch Ministry Partner. As a ministry partner, Tim will continue to use FaithSearch resources as part of his “ministry toolbox,” proclaiming the Gospel with evidence in northern Minnesota.
