I do not know the timeframe of this decision but from possibly every perspective biblically, morally, emotionally and just bloody common sense, your decision to stay put was the Right One. I cannot fathom anyone or anything from the true God to attempt, suggest or convince otherwise.
After six months in college, I considered going WOW and forsake the college education my parents prepared for me since birth. At that time the WOW program was new and the excitement of witnessing and studying the Bible fulltime promised to be an adventure to my youthful ideals. I went to the local TWI leadership as a sounding board and for advice regarding this major decision. Should I commit my life to God as a WOW Ambassador or continue my college education? After some discussion and prayer, I was advised to stay in school since many did not have the opportunity I had with a prepaid college education. If I did not like my current major, then change majors; if I did not like my current school, then change schools. I was further warned that if I decided to quit school and go WOW, my parents would be greatly disappointed and be bitter toward the Word for the rest of my life. I stayed in school and later participated in the College WOW program which was one of the greatest experiences of my life. To this day, I fondly remember my college experience which include sharing God's Word, living with other Christian college students, witnessing God's healing power and enjoying a great relationship with my parents. I remember recounting this milestone with Dr. Wierwille years later in the Clubhouse and he agreed it was the right decision. We laughed together that it appeared as a major dilemma because my youthful impatience. There are moments in our lives when a major decision involves multiple factors to consider which attempt to tug us in different directions. I always believe and if you can step back and approach a decision with prayful consideration, and sometimes simple common sense, you will arrive at the best conclusion. IMHO, there is no comparison between your family's well-being and your absence in a program for a year. Enjoy.
