Presenting evidence of things seen, to strengthen our faith – the evidence of things not seen.

My ministry can benefit anyone in any stage of their relationship (or lack thereof) with Christ.

* It can give non-believers solid reasons to trust the Bible and put their faith in Christ. It removes the roadblocks, excuses, and doubts.

* It can encourage new believers to grow in their walk with Christ and trust in His word, with confidence their new found faith is in something real.

* It can thrill and encourage even the most seasoned saints to see evidence confirming the truth of the scripture.

* It can make backsliders realize the Bible is true, God is real, and they’d better take them  seriously, because they will give account to a holy God.

I require no guaranteed amount for an offering. I operate on a FREE WILL OFFERING basis. I will accept whatever the Lord will provide. I have held meetings at many small churches, sometimes less than 20 members.

In fact since I retired in May 2022, I can no longer accept anything that would be considered “income“. If I go over the limit, I lose an entire month’s social security. I work part-time and the company I work for pays me right up to my social security limit. I can accept expenses. My wife is a BJU/U of N.O. trained musician (Master’s degree in voice and music instruction). Churches can give her as much as they want without affecting my income limit. Churches that are not 501c3 can do whatever they want.


I’ve been preaching on creation related issues for 20 years, full-time since mid-2013. I’ve preached creation messages in three foreign countries (Poland, Russia, Mexico) and about half the states in the US.

I’ve done university-level seminars along with Ph.D. scientists, spoken for creation science organizations, preached in churches, done week-long revivals, VBS, King’s Kids youth programs, and more.

I’ve been a member of Wyldewood Baptist Church Oshkosh, WI since 1989 (over 30 years). I have preached and taught dozens of times there to adults and kids.

I’ve taken creation research trips to Mt. St. Helens, the Paluxy River (Texas), Niagara Falls, riverbeds in Dayton, OH (fossil collecting), AIG’s Creation Museum, ICR’s Discovery Center, and Joe Taylor’s Mt. Blanco Fossil Museum.

* A.A. in applied arts with honors and member of National Dean’s list, Finlandia University. 2nd in class in cellular biology (Prof. Donald Walhalla). 1st in class in general science at East Detroit High School (instructors Maata, Jasina).
