Jack and I first met when I attended a 6:30 am Christians in Commerce Meeting at the San Jose Chapter. I can't recall entirely how it worked out that we ended up grabbing lunch together soon after, but we did. Jack is the refreshing type of believer who lays it all on the table, his shortcomings, his struggles, and mostly, his praise.
I've come to Jack with some of my own struggles as a result, and he is a rare person in that he shies away from giving advice. He wrote to me once:
"I'm not one to give men advice, because God has assured me that His voice to each heart is far more impacting than any knowledge I may impart. He does use me to speak to folks, but not usually in the way of advice."
He may share a relevant story, but usually doesn't say "do this or do that." I've found that when I go to Jack, the Holy Spirit moves through him to me in a profound way.
Jack and I have had several such "Holy Spirit exchanges" between us over the past year or so. One such case was a breakout of prayer in the middle of a Denny's restaurant I wrote about here. Most recently, though, the Holy Spirit moved through Jack as he spoke at his wife's funeral. She passed away unexpectedly, after 40+ years, I grieved in my heart for him, and I knew that God would use this difficult trial for his glory. Jack's words were profound, about his failings and love for his wife, it became clear their marriage was a great testimony even to, no, especially in, the last days.
Jack has a website where he blogs and provides resources online here. I really like his "Appointment with God" outline he has posted online here. As Jack shifts from career as a successful salesman to spend more time in ministry, I expect God is going to do amazing things through him, I know he is going to finish the race running hard.
