As a teacher, person of faith and lifelong learner, I sometimes explain my faith to others as a ‘working hypothesis’. By this I mean that my faith is based on the ‘best I’ve worked out to this point’. This ‘best’ is important. It is how I ground my thinking and my beliefs. It is the clearest understanding I have as to how things work, and what really matters. It represents my commitment to the ultimate purpose in this world.
