Me: If people don't believe in absolute truth does that mean it does not exist?
Student A: It doesn't exist for those people who don't believe it.
The Ever-Patient Me: That's not what I asked. Does absolute truth exist even if people don't believe it?
Student B: It must. It's like Christianity. There are many who don't believe Christ is true God and true man. Believe it or not, Christ alone saves. Christ is the world's Savior. That absolute truth is undeniably true even if people deny its truth.
At this point I strolled to my desk and picked up God Grant It, Daily Devotions from C.F.W. Walther and read from the day's devotion: Thursday of the Eleventh Week After Trinity:
Whoever has not experienced any of the pains of true repentance, whoever has not yet felt the force of the Law and regarded himself as a sinner through the enlightenment of the Holy Ghost, whoever has never groaned for the depths of his distressed heart of Christ’s grace, and whoever still fails to recognize that a person cannot believe in Christ by his own powers but alone by the working of the Holy ghost is certainly still without faith. The birth of faith in the soul of a sinner cannot leave him unmoved. Indeed, it is a work that transforms the whole person – from darkness to light, from spiritual death to spiritual life – and brings him out of powerlessness into a divine strength.
And this is precisely why I love teaching in a Lutheran school.
