A Jack in the Box represents surprise for the unsuspecting person or can even provide an element of surprise in timing for those who know what is behind the Jack in the Box lid. In the same vein no one in our lives is 10O% there for us and no situation is 100% predictable. Jesus knows this of all mankind and life on earth (Luke 22:34). Jesus came to give us total security. We can actually trust that Jesus is 100% there for us 100% of the time .
