Soren Kierkegaard was a Danish philosopher and theologian. He was born May 5, 1813 and died November 11, 1855. During his lifetime, he wrote a number of books. In 1848, he wrote 
The Sickness Unto Death. In the book, Kierkegaard discussed the idea of despair, which he equates to the Christian understanding of sin. Kierkegaard believed that if an individual did not align himself with God or the ways of God, despair would be the result.
Some years ago, a friend gave me a quote from this book that I have kept and read occasionally.
The trouble is not that Christianity is not voiced . . . but that it is voiced in such a way that the majority eventually think it inconsequential . . . . Thus the highest and holiest things make no impact whatsoever, but they are given sound and are listened to as something that now, God knows why, has become routine and habit like so much else.
AMEN! Basically, the question that some ask is, “What difference does Christianity make?” And if our presentation of it isn’t compelling then it becomes just one choice among many.
