The first thing that caught my attention when I opened Stephen Trombley’s book – Fifty thinkers who shaped the modern world, is a quote by Thomas Hobbes, Leviathan (1651): “Leisure is the mother of philosophy.” After that, I wanted to know the first-person Stephen profiled. He was Immanuel Kant (22 April 1724 – 12 February 1804), a German philosopher who is regarded as the central figure in modern thoughts. Immanuel who was raised in a church that placed emphasis on “studying the scriptures as a basis for personal devotion, the conscientious practice of Christian ethics etc..” sadly, rebelled against his parent’s way of life and instead he was influenced by a professor of logic and metaphysics at varsity. Linking the quote at the beginning of the book and how Immanuel turned out, I concluded that how he spent his leisure time might have influenced who he later became. We must be intentional about how we spend our leisure time. We must ensure that the books we read, the people we talk to or the media that we consume do not directly or indirectly change our core beliefs. We must never doubt Biblical inerrancy and we must beware of being deceived or letting our minds to be led astray from our simple and pure devotion of Christ. So, whatever we may be doing or wherever we may be, including during our leisure time, we should be conscious of our position in Christ.
