“It has been customary to employ the category ‘doubt’ where one ought to speak of ‘offense.’ The relationship … to Christ is not either to doubt or to believe, but either to be offended or to believe.”
— Søren Kierkegaard,
Training In Christianity
I have said this before, and I’ll say it again: the opposite of faith is not doubt.
Doubt dwells with faith, just as stress dwells with growth. Growth of muscles happens by straining them. Growth of skills happens by them being tested. We become by overcoming. Faith needs stress, needs tests, needs stretching into new areas, needs maturing — and where this process is happening, doubt will be present as well. It is the thing faith needs to conquer.
The uncertainties of life are the gymnasium of the soul.
