Tim Kolb

Tim Kolb, known to most simply as “REV”, is a writer, teacher, itinerant minister, and Vice President of the Northwest Arkansas Tribe of Judah Motorcycle Ministries. He primarily ministers to the outlaw biker community, carrying the message of grace into places and lives often overlooked by the church. At the same time, REV is just as comfortable behind a pulpit, teaching and equipping the Body of Christ with clarity and power.

An ordained minister with formal biblical training, REV brings both experience on the streets and depth from study. He is also a student with Bethel School of Supernatural Ministry (BSSM), a volunteer with Bethel Church Online, and the voice behind Big Rev 1: The Grace Underground. His heart is to make grace practical, approachable, and life-changing for everyone.

Beyond ministry and writing, REV is a devoted father and proud grandfather. When he’s not on the road speaking or writing, he invests in family, creative projects, and encouraging others to experience the fullness of God’s presence and purpose. The Genesis of Grace is his first published book.
