Tom, your post has stirred some heartfelt responses and your doubts reflect what many go through at one time or another. My husband rejected faith and was agnostic until he decided to investigate reasons for believing versus not believing.
After examining scripture, science, testimonies, historical evidence and anything else he could study, he concluded that Christianity was truth and decided to believe. His earlier doubts and quest for truth have helped him to respond when others express doubts, because he experienced what they are going through and he approached belief vs. unbelief in a methodical, logical manner.
My faith is primarily emotional, more a “feeling” or awareness of God’s presence, whereas his is almost devoid of the supernatural but very much based on logic and reason.
Continue to embrace your doubts without disparaging either doubts or faith, and keep your mind open to God’s work in your life.
