Some of us like the idea of living an adventurous life, Bill and Yoka certainly have had a fair share of excitement and this book documents their story. Most people live within the safety of their comfort zones but Bill and Yoka have not hesitated to step out in faith and found that obeying God is the most fulfilling adventure anyone can embark upon. Bill and Yoka, both originally from Holland, are a couple that set out to achieve a vision from God which was birthed in their hearts over two decades ago. This book is a chronicle of their life of faith; recording some of the miracles that God has provided along the way; but also giving us some insight into how those miracles were desperately needed and what it meant when God came through for them. Pastor Stephen Holt Melbourne, Australia. "Yoka, I just wanted you to know what a blessing it has been to read Treasures in jars of clay. Just to read of your faith and to see how God has provided for you was wonderful. I found the book extremely motivating and also very honest and I really loved it. I see that over the years, you and Bill have had a large number of people come into your life and who can know how God has used these meetings to further spread His love and the Gospel throughout the world. I am one of many who have been influenced by you. You and your story have contributed to me being able to have a spiritual boost and a renewed vision which has given me extra confidence to in turn be able to be available to help others in my 'mission field' using the unique abilities, personality and talents God has given me."
