I came to trust in Jesus as my Savior after a two-year personal study of the Bible that convinced me that Scripture is free of contradiction and error - doctrinally, historically, and scientifically.
Logically, taking Scripture seriously means being passionately concerned about interpreting it correctly and thus welcoming any evidence that exposes erroneous understandings of the biblical text. Unfortunately, many zealous Bible students and teachers confuse their favorite interpretations of the Bible with the Bible itself.
To insist that belief in the Bible demands belief in a young Earth is to put a stumbling block in the path of many nonbelievers. It raises the question of why a God who is committed to revealing truth would make the universe and Earth measure to be old if, in fact, they are not.
The scientific content of Genesis 1-11 holds special significance for me because it revolutionized my thinking and, thus, changed my life's direction. Until I reached my late teens, my singular passion was science, astronomy in particular. My life's purpose was to learn more about the universe; nothing beyond that really interested me.
Sticks and stones may break bones, but words do more damage than most people can imagine. Especially name-calling. 'You're dangerous!' 'Deceived.' 'A false prophet.' 'A compromiser!' Charges like these by young-earth leaders, both spoken and implied, are intended to discredit, maim, and crush old-earth advocates, including me.
The earth's history over the past several million years is that for every 100,000 years, we go through a dramatic climatic cycle where we get 90,000 years of ice age and 10,000 years of a warm period. I think people today just have the expectation that we deserve a perfectly benign climate forever.
