Kierkegaard on following Jesus
"If someone wanted to be his follower, [Jesus] said to that person something like this, 'Venture a decisive act; then you can begin, then you will know.'
...Once you have ventured the decisive act, you are at odds with the life of this world. You come into collision with it, and because of this you will gradually be brought into such tension that you will then be able to become certain of what Christ taught. You will begin to understand that you cannot endure this world without having recourse to Christ. What else can one expect from following the truth?"
