Howard''s interests include planning, leading and evaluating worship, preaching, and worship renewal throughout the evangelical church.

"My life-long prayer, from my days as a child, was that I might be honored to serve as a Christian Reformed pastor preaching the Word of God to encourage and challenge his people. I consider the forty years of my pastoral ministry to have been the most valuable way in which I could have invested those years! When I consult with pastors, teach and mentor students, hold conferences for worship leaders, or write worship planning materials, my aim is to equip and inspire others to serve their Lord and Savior by making a whole-hearted investment in his church and his people. Such ministry is certainly not without its stresses and discouragements, and those of us who have found such joy in a life-time of ministry are uniquely fitted to encourage others."

Howard lives in Hudsonville, MI with his wife Eleanor.  They have three married sons and ten grandchildren ages 5 through 19. His hobbies are yard-gardening, walking, photography and model railroading.
